Dear Maintainer,
Many applications fail to start on my PC wuth a Segmentation fault (ffplay
mplayer kdenlive obs-studio)
Each time, the core file seems to point an issue with the
/usr/lib/x86_64-linux-gnu/dri/iris_dri.so library:
Core was generated by `ffplay /home/clohr/test.mkv'.
Program terminated with signal SIGSEGV, Segmentation fault.
warning: Unexpected size of section `.reg-xstate/338339' in core file.

Some info about my graphic card:
# lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics
520] (rev 07)
As a workarround I use the following environment variable:
export MESA_LOADER_DRIVER_OVERRIDE=i965
Best regards
