I was able to reproduce the issue after a 30 min browsing session viewing many videos on 102.0a1 20220526093328, here is the perf profile using the graphics preset: https://share.firefox.dev/3wMd5DM Also, there are no errors reported on about:support. I could try inspecting the browser with RenderDoc, but I will have to try to reproduce the issue which can take very long or does not happen at all on some sessions.
