Youtube dropping frames constantly

[dohh]

After much searching through these forums and trying all the fixes proposed I really can't figure out what's wrong with my browser and Youtube videos. This wasn't happening before, but I'm not sure which update changed it because I keep the browser up to date and most of the time I'm not watching videos on this desktop PC, using an older build isn't really a solution anyway.

Videos play perfectly fine, even 4k60fps, in Firefox. I've tried disabling/enabling hardware acceleration, I've tried Youtube in a clean Vivaldi profile and other typical suggestions but nothing worked.

Here's the vivaldi://gpu report:

padBuffersToMaxVertexAttribStride (Vulkan workarounds) anglebug:4428: Disabled: isAMD
Vulkan considers vertex attribute accesses to count up to the last multiple of the stride. This additional access supports AMD's robust buffer access implementation. AMDVLK in particular will return incorrect values when the vertex access extends into the range that would be the stride padding and the buffer is too small. This workaround limits GL_MAX_VERTEX_ATTRIB_STRIDE to a maximum value and pads up every buffer allocation size to be a multiple of the maximum stride.

//MODEDIT: could be related to:

• Hardware acceleration issue
• YouTube buffering
• Display driver artifacting on YouTube fullscreen.
• YouTube window to fullscreen is REALLY slow
• Video stutters while in full-screen at 2x speed
• Is Microsoft slowing down Vivaldi on purpose?

[mib2berlin]

@dohh
It seams you have disabled HWAcceleration for this test, enable and restart Vivaldi.
Please edit you post and put the marked output of ://gpu in </> code view, it is much easier to read.
Add your Vivaldi and Windows version, system specs (GPU´s), please.
Is Vivaldi running in a virtual machine?
Maybe after an update your GPU is not supported anymore, you can try to open chrome://flags and search for Override software rendering list, enable it and restart Vivaldi.

Cheers, mib

Sorry about the pasted log, apparently you can only edit posts for 1h after posting so I can't fix it.

GPU is AMD 5700 XT, Vivaldi is up to date and OS is Windows 10 21H1 (19043.1466). I was only trying the HW acceleration setting through the flags page, but I just tried it enabling it in the regular options and no change. Videos are literally unwatchable like this, more a slideshow than a video.

@dohh
Hm, the 5700XT is a modern and powerful card, must be something else.
I can watch Youtube 4K videos fluently on a much lower i5 HD 620 integrated GPU system.
I just guessing now, it is a third party security software and/or an extension blocking Vivaldi.
May you can check with a guest profile, it exclude all settings and extensions.

https://help.vivaldi.com/article/guest-view/

For the second, disable security software for the first.
I had a lot of problems with Avast on a friends PC, after disabling it Vivaldi run fast a hell and other errors disappeared.

I've tried with a clean profile and no changes, just tested the guest profile and it's the same. I'm not using any AV software.

[mib2berlin]

@dohh
I am sorry, I am a bit out of ideas now.
Firefox use complete different render engine and own video codecs, Vivaldi use Windows codecs.
May you can check with Chromium, make sure you have the same build number or close. Vivaldi stable use Chromium 96, the snapshot is at 98.
If Chromium does not work too it is may a codec problem.

Just tried with Chrome 97, then it updated to 98 and both play 4k60 videos with no drops... I'm also totally clueless about this issue.

Gotcha, just tried Chromium 96.0.4664.0 and also the latest one which is 100.something. Both ran videos perfectly 4k60 so I guess this rules out local codecs as the culprits on my PC??

[mib2berlin]

@dohh
I guess so and I am sorry but now I am really out of ideas.
Maybe other user steps by with more inside to Youtube issues and Vivaldi.

[jcaesar]

I'm having this exact same issue as of the last 3 weeks or so.

windows 10, RTX3060 on latest drivers, tested other devices and firefox ect to confirm its not my internet

is this ongoing for you? @dohh

[thebobbu]

Yep, I'm seeing this again as well. I had it a while ago, seemed to have gone away with some Vivalid updates, but since refreshing my Windows install today it's dropping about 50% of frames. Definitely some issues specific to Vivaldi here that could use some work, given the last time I had this issue was back in March, and it seems to be recurring.

[Alphaprot]

I will hop onto this thread aswell, though with an iGPU (Intel Iris Xe Graphics on a i7-1165G7) as compared to the more-capable dedicated GPUs the other users have installed.

At least for me it seems like the issue is not due to extensions (guest mode shows no signs of improvement), but rather due to the Chromium 114 foundation being ineffiecient at decoding videos with my setup.

I tested the current Vivaldi built with and without hw-acceleration enabled as well I tested the archived Win64 version of Chromium 1140001 with and without hw-acceleration.

Both lead to core temperature values of 85-100 °C (Source: HWiNFO64, mean DTS-sensor value of all four cores) and frequently entering thermal throttling of the core.

I then tested with the newest (117.0.5928.0) dev build of Chromium which leads to improved performance.
Temperatures fell to 71-87 °C, without hw-accelearation they are about the same as with acceleration enabled, but there are micro stutters (e.g. movements appear choppier and not fluent)

Interestingly, the occurence of thermal throttling goes up with hw-acceleration enabled, which I first thought was the main issue of the decreases performance.
However, even when hitting the limits of the thermal envelope, I am now able to watch 4k YouTube videos without entering "slide-show-mode".

Please let me know what logs and/or further information are valuable here.

@Alphaprot
Hi, I have no issues with older Intel hardware with Vivaldi 6.1, streaming 4K 60 FPS, it lags a bit but no frame dropping.
You can test this with install the snapshot version of Vivaldi 6.2 as standalone install, it is based on Chromium 116.
If this work the next update will fix your issues.

Keep in mind the most issues in Vivaldi are caused by extensions and third party security software.
Edge/Chrome work fine but Vivaldi lags, this is happen often after an update of Vivaldi.

Hey mib,

thank you for pointing me towards the pre-release of 6.2, which seems to fix the issue for me.

Now it appears that HW-based decoding works as inteded, as the "Decode 0" (the Core i7-1165G7 seems to have two decoding units) shows some load now.

In previous scenarious (Chromium 114 based, hw-acceleration on), the load was mainly on the 3D GPU core which might have resulted in some performance problems.

I do know that proper/reproducible bug reporting requires to disable extensions and other factors, that's what I tested previously on the guest profile without extensions.

Best regards and thank you,

@Alphaprot
I am glad it work for you!
We should not but I use the snapshots for my daily work and the stable only for testing issues reported from users.
You will get the latest features but sometimes also new bugs, reporting new bugs and issues make Vivaldi stable better.

Backup my profiles and use sync keep me from data loss since version 1.0.

Cheers, mib
