After upgrade to Ubuntu 20.04 most KDE native apps are now crashing and
this includes systemsettings5. segfault stacktrace points to crash in
/usr/lib/x86_64-linux-gnu/dri/iris_dri.so
> inxi -G
Graphics: Device-1: Intel HD Graphics 530 driver: i915 v: kernel
Display: x11 server: X.Org 1.20.8 driver: intel resolution:
3440x1440~60Hz
OpenGL: renderer: Mesa Intel HD Graphics 530 (SKL GT2) v: 4.6 Mesa
20.1.8
xserver-xorg-video-intel version 2:2.99.917+git20200226-1
Setting MESA_LOADER_DRIVER_OVERRIDE=i965 does resolve this issue
completely, however I am wondering why this is not selected
automatically if iris driver does not support my GPU.
