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?
