Hardware encoding H264 by VAAPI crashes the computer (Intel HD 2000)

Hi, I encountered an error while trying to hardware encode to h264 with spectacle, obs and even ffmpeg. Every time I start encoding the system instantly crashes, becoming unresponsive and generating artifacts on the screen, until the session terminates itself and returns me to SDDM or I’m forced to force shutdown my computer. However Vaapi decoding on mpv and even on Firefox/Chrome works perfectly. I use KDE on Wayland but it's the same result if I started on x11.

lspci –v

Link to journal of the crash
journalctl -b-1

the command that causes the crash (it doesnt produce any errors on logfile after crashing)

ffmpeg  -vaapi_device /dev/dri/renderD128 -i asd.mkv -c:v h264_vaapi -c:a copy -vf 'format=nv12,hwupload' asd2.mkv  -loglevel "repeat+level+info"

I also tried different versions of mesa (mesa,mesa-git,mesa-tkg-git), mesa-amber(doesn't even start SDDM) and libva-intel-driver (libva-intel-driver-git) with the same result.
Encoding isn't that important to me but I'm kinda curious about why is this happening. Tell me if I need to provide any other log. Thanks

Do you have the same problem on an X11 session?

Yes, I do have the same problem if I start KDE on a X11 session, with or without xf86-video-intel.

Are you using mesa-amber ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
