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:
firefox killed by SIGSEGV
)* #1 [iHD_drv_video.so] OsContextSpecificNext::Init(void
, int, int*, int*) [clone .constprop.0]* #2 [iHD_drv_video.so] DdiMedia_InitMediaContext(VADriverContext
#3 [libva.so.2] va_openDriver
#4 [libva.so.2] vaInitialize
#5 [libxul.so] mozilla::FFmpegVideoDecoder<58>::CreateVAAPIDeviceContext()
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?

@taylenismable In Firefox forums plugins are mentioned as cause of this. try a clean Firefox start.,

It’s because you have enabled VA-API which does not work correctly and it’s still an experimental feature. Please disable it (it’s off by default).
Also please file a bug at
bugzilla.mozilla.org for further investigation.

Can this be disabled using
about:config by setting
false (if it’s not already)?
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.
Again, thank you all for the help!
