There is an interesting development: One one machine with a NVidia card (and dual monitor configuration) I've switched from the proprietary driver to the open source one nouveau
[01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [NVS 310] (rev a1)]
With the proprietary driver I was experiencing those slowdowns that were ending with a complete browser freeze but no crashes.
With the
nouveau driver I am getting Xorg crashes
every time I play a video on youtube (which I think is good news because now at least the bug should be traceable).
Again Brave and Vivaldi work fine with youtube with both the proprietary and the nouveau driver. Hardware acceleration is always enabled.
If I play videos which are embedded in other web pages (like here for example
https://hackaday.com/2021/06/13/roller- ... yote-style ) video plays fine in palemoon. If I click watch on youtube, the same video crashes the entire Xorg.
Youtube videos do play for a few very short seconds before crashing Xorg.
