I have a problem with Firefox after the upgrade - certain sites crash few seconds after I open them (one of them is Twitch, Youtube for example is ok though), logs show the following error:
I have a laptop with Intel tigerlake CPU (no discrete GPU) and I think new Intel driver was enabled by default in Fedora 35, could that be the cause of the issue?
Thank you everyone for the suggestions. After checking it seems like this was caused by the media.ffmpeg.vaapi.enabled flag, which is a bit weird as it hadn’t cause any issues for me before the upgrade Fedora 34 → 35.
I guess since media.ffmpeg.vaapi-drm-display.enabled is still enabled I appear to have HW decode working (low cpu usage when watching Twitch/Youtube), so it’s not a big deal anyway.
