Description Leyenda 2020-06-07 10:33:17 UTC 
SUMMARY


STEPS TO REPRODUCE
1. Use the gpu from a amd Ryzen 5 2400g cpu, with Radeon Vega Graphics
2. Use a 5.6.x kernel and kwin-wayland from plasma 5.19 and master
3. Browse the web with firefox flatpak

OBSERVED RESULT
When a graphic error from amdgpu driver occurs, plasma crash and logs out to sddm, ending your session.
That doesn't happen on x11, there when an error occurs x11 restars itself withouth any problem.



EXPECTED RESULT

It seems to not crash to SDDM anymore. But it doesn't inform about a graphical error when it happens.
