Hi, there are some things/settings can slowdown Vivaldi:Thanks.
Long list in downloads
Possible. I haven't done anything about it.
Huge history
Possible. I haven't done anything about it.
Many notes with screen shots
I have only one note, I think.
Animations (Appearence settings)
I haven't touched that setting.
Smooth Scrolling (Webpages settings)
I haven't touched the setting.
Hardware acceleration (UI slow when enabled)
I haven't touched the setting.
Some pages act strange with Vivaldi on scrolling, https://www.wissenschaft.de/ for example.
I don't see anything strange on the page, but scrolling on it is as laggy as on other webpages. It scrolls fast on Chrome and on a fresh profile of Vivaldi. (By the way, I guess it's a science page, isn't it? Looks fun.)
In short, everything on your list has been left default. I'll try to go over your list one by one (like deleting history) to see any of them improve the speed.
Cheers,

Any extensions or flags enabled?
The sluggishness doesn't go away even when all the extensions are disabled. As in my response to mib2berlin, I don't remember customizing anything that would affect the performance. I just move my tabbar to the left-hand side, change the theme to one of those dark themes, switch on the flag that make a new tab automatically form a stack, enable Sync, and I think that's about it.
For a particularly sluggish site, I created a new profile for it and it's not sluggish at all on it.
Cheers,

It's interesting that on a website which loads rather slowly, I can't start to scroll until the loading nearly ends on my main Vivaldi profile. On a fresh profile, I can start to scroll right away even while the page is being loaded rather slowly.
I've cleared "Browsing History", "Downloads", "Storage", and "Cache" and restarted Vivaldi. The sluggishness stays (all extensions have been disabled).

Hi, it was meant as "Touch it", delete DL list, switch off animation and so forth.Cheers, mib

Okay,
- switching off hardware acceleration has made the scrolling within the tabbar a lot smoother.
- it has mixed results for webpages, though:
- Some pages takes some time to load, and while it's loading, you can't scroll within it. (On a fresh profile, you can.)
- But, once the page is fully loaded, the scrolling is fast. (It was laggy before the switching-off of hardware acceleration.)
Has some lagginess due to hardware acceleration reported? Is it new?
On the other hand, I haven't noticed any change when animation is switched off. It remains off for now.

I closed all but two tabs and this problem is gone.
There seem to have been two elements in this issue:
- Scroll itself is extremely laggy → This problem was gone when hardware acceleration is switched off.
- Loading of pages is slow and during the loading you can't scroll. ← I couldn't fixed this.
Both problem happened even when the background tabs were hibernated. Neither problem happened in a fresh Profile.
I've switched hardware acceleration back on but still scrolling is fine.
So, somehow hibernated tabs interfere with the performance of the active tab. Perhaps they keep some resources, such as network connection and GPU memory, to themselves even when hibernating?
-
Now it's getting weirder.
The above problem was actually on my main Profile. It had 60–80 tabs and I thought that somehow was causing the problem.
I use two more Profiles and one of them has started to develop the laggy-scrolling problem. It has only about 25 tabs.
As I write this, I close them one by one and test the smoothness of scrolling on a particular webpage. It gradually gets better and better (subjectively). When the total number of tabs is down to 5, I stop noticing lagginess.
I'll use Vivaldi with minimum tabs for a while.

Hi,
I'm on the latest of MacOS Catalina and Vivaldi (at the moment there are about 30 opened tabs) and confirm, that switching off HW Acceleration eliminates the effect of laggy scrolling. Also, I don't see notable impact neither on energy nor CPU usage after switching HW acceleration off.
Thanks.
-
@doka380 What model Mac do you have? (might be others who can also test it with the same hardware)
-
I have the same issue. Scrolling has been really laggy on any web page, and even typing is kinda laggy as well.
-
Someone at Vivaldi needs to check the meaning of "acceleration". Right now when it's on scrolling is very laggy, switch it off and it's much better. On the other hand things like videos are slower, so it's one or the other.
This is not an issue with Chrome, on which Vivaldi is based - with hardware acceleration, scrolling is smooth and videos too. There's no need to compromise between one or the other.
-
I've noticed that video playback in general is significantly slower on Vivaldi compared to Chrome (checked both Windows and macOS, on recent laptops). On Chrome it's smooth, probably around 24fps, but on Vivaldi it's visibly jerky, probably around 15fps. Changing the acceleration options make no difference.
For now I'm going back to Chrome since I care more about basic performance than all the features that Vivaldi offer.
-
@laurent22 Can't say for MacOS, as I don't use it, but at least on Windows I can confirm that video playback is smooth - I have no issues with watching videos @ 60 FPS in Vivaldi, there are no dropped frames, no lags, or anything. Scrolling is also very smooth. I guess there are various factors that may play a role here - such as the hardware, drivers, other software, etc.
-
@pafflick It depends on the codec, I know Edge (on Windows 10 & 11) has broken play back of HEVC (h.265).
On macOS it seems to depend on the model & macOS version, and extensions.

I experience very noticeable laggy scrolling on my macbook, unfortunately.
One thing I do notice is that when a webpage is newly loaded, it scrolls smoothly. When I switch to another tab, and then come back, the webpage will become very laggy to scroll.I'm happy to help the Vivaldi team to debug if possible.
My system information is attached below:

@samuelli First, follow the Troubleshooting issues guide, to exclude the possibility that there's something broken in your profile/configuration. Only after that, you can report a bug (if you manage to reproduce it consistently).

Was there ever any progress on this? I used Vivaldi on my Mac, and when I switched to Windows, I wanted to continue, but there were issues with tabs crashing on specific websites (Reddit, etc.), so I've been using Firefox for awhile, checking back in with Vivaldi every now and then to see if the crashing had gone away. It really is the nicest browser, IMO.
Today I fixed an issue with media codecs on Windows, and suspected it might be related with the Vivaldi crashing issue, so I checked back in and haven't seen any crashes yet, though TBH I only really checked Reddit and some German site that another user said was crashing.
Anyway, I'm rambling, sorry. I noticed quickly that scrolling was very choppy, even compared to Firefox which is generally a bit slower than Chromium-based browsers. I have a 90-Hz panel, and scrolling is crazy butter smooth in Vivaldi when the issue doesn't surface, but very choppy when it does. Reading this thread, I tried the different things suggested, and also tried forcing iGPU vs. Nvidia GPU in the Windows settings, but nothing worked.
As another person stated, hibernating background tabs has no effect. And the number of tabs has a direct correlation with the severity of the issue - but only within the active profile.
Allow me to elaborate. Currently, I'm writing this in my normal user profile in Vivaldi. I have 44 tabs open in total. Scrolling is very choppy. Hibernating background tabs has no effect.
If I open an extra window in this profile, and go to this same webpage, the scrolling remains choppy in the new window. If, however, I open a private mode window and open this page there, scrolling is buttery smooth. Note that the other 44-tab window is still open.
If I now, in this private mode window, google something random and start opening search results in new tabs, scrolling becomes increasingly more choppy. But if I open another private mode window on top of this (we now have three windows, with perhaps 100 open tabs in total) and again open this webpage, scrolling there is buttery smooth again.
I was actually going to suggest that this indicates that it's a problem that "infects" the profile in some way, as I assumed that opening two private mode windows would result in two private sessions, but I just discovered that actually the private mode windows share the same private session. So that makes it a little more strange, but perhaps then also easier to debug?
Just to boil it down to bullet points:
- The more tabs I open, the choppier scrolling gets, regardless of hibernation status of other tabs.
- In non-private mode, opening a new window on top of the choppy one yields the same effect: Scrolling remains choppy.
- In private mode, opening a window on top of the choppy one yields the opposite effect: Scrolling is buttery smooth once more.
The fact that I can open an extra private mode window and get wonderful scrolling when the normal mode performance becomes terrible indicates that this isn't resources related, as in it's not just that my CPU or GPU is bottlenecking. The fact that I can open another 50 tabs and destroy scrolling in this additional window and THEN open another windows on top of everything and again get beautiful scrolling just underlines this conclusion.
I'm wondering if people just don't notice this. If I plug in my Logitech mouse and use the scroll wheel in its "clickety-clack mode", it's not as apparent, since each "clickity" and each "clack" moves the viewport some fixed amount of pixels. If I switch to its "free-running" smooth mode, it becomes immediately apparent. Also it's very apparent when using my precision touchpad, which is what I do most of the time.
Could someone who doesn't experience this problem try to do this, preferably with a (precision) touchpad where you "fling" the page when you scroll (I believe they call it "inertia?"):
- Open a new private mode window (Ctrl+Shift+N), and open this exact thread there. Scroll up and down. It should be smooth as delicious butter.
- Open another tab in the same window and search for something on google. Start opening all search results in new tabs, and for each page of search results, go back to the initial page and observe the effect it has on scrolling performance.
Does this not eventually cause a lot of stuttering when scrolling? If not, that sucks
Well, it's great for you, but sucks for us to whom it has this detrimental effect 
If it does, then:- Try hibernating all background tabs and confirm that this has no positive effect.
- Then try opening yet another private mode window and again open this thread's page there. Is scrolling not again smooth?

Disabling the Hardware acceleration helped me on 2019 mac pro (intel) monterey. Fresh install of vivaldi 6 tabs open only 2 extensions and scrolling was very choppy (especially on github). Disabling hardware acceleration is a night and day difference.
-
Having the same issues on Windows 10 19042 with an AMD Ryzen 3700X
Disabling Hardware Acceleration did temporarily fix the issue for me, but got even worse after, in my case, GitHub loaded fully.
I'm surprised this hasn't been addressed yet -
Vivaldi 5.4 is out https://vivaldi.com/blog/vivaldi-5-4-on-desktop/
If it is still crashing try clearing out the cache for all time
