Comment 19 for bug 1876219

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

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.
