Solved Video rendering glitches

Gregor

Hi, I have these weird video glitches on some website with videos, like https://www.qt.io/product/qt6

It's also weird that it only occurs at the beginning, then after some time it disappears.
Also it works fine in Firefox and was not present in Vivaldi on Windows 7.
What can be the reason?

V 5.7.2901.3
Windows 11
latest graphic drivers

I updated the browser and so far it has solved the problem. I also earlier deleted cache folders (Cache, Code Cache, GPUCache, Service Worker) so maybe it also helped.

Based on the version number looks like you are using a snapshot build.

Also is hardware acceleration on or off?

Gregor

If you mean Settings/Webpages/Use hardware acceleration when available, then yes it's enabled, as always.
It started after I recently changed cpu, mobo, ram, Windows from 7 to 11 and new graphic drivers. Never had this issue before.
Similar glitches occur on YouTube or some VOD videos, also on clear Vivaldi profile. On Win7 and previous hardware config with the same snapshot no problems.

Hi, please update to Vivaldi 5.7.2914.3, there was many bug fixes since 5.7.2901.3 and also an update to Chromium 110 which can change a lot.
For Nvidia cards some user fix UI glitches and video issues with disabling VSync, I guess there are similar settings for other GPU.

Cheers, mib
