[Software] Firefox randomly choppy video playback (regression)

Hi there

I'm new to Debian and to this forum. I have a problem with Firefox under XFCE, with amdgpu driver, the video playback is randomly stroboscopic for a fraction of second.

I have a previous Linux system installed on the same machine, using an old Firefox 96 which is not affected. The problem appeared when I installed the latest Firefox release.

I thought it was due to my outdated system, so I've installed Debian 12 on another drive, unfortunately I have the same problem using latest Firefox ESR.

It seems to be a regression somewhere between Firefox 96 and 128.

I think Wayland became the default with Firefox 121, then I wonder if I need to set an environment variable or a setting in about:config to get a better rendering with Xorg.

Any clue would be greatly appreciated because I have no idea how I can troubleshoot such a problem.

Thanks in advance.
