SUMMARY The Plasmashell desktop and it's process crash when I power off and then power on the monitor under Wayland on a Radeon RX 570 graphics card. The desktop and it's panels disappear but the running applications and Kwin didn't crash. I'm using Debian unstable with self compiled packages created from current master git branch. Using the same packages on another machine using an integrated Intel graphics card, plasmashell didn't crash and continue to work as expected. STEPS TO REPRODUCE 1. Power off and the powering on the monitor on Plasma under Wayland on a Radeon graphics card. OBSERVED RESULT The plasma desktop and it's process crash and disappear, but KWin and the running applications didn't. EXPECTED RESULT Plasma desktop should not crash, as it didn't crash on the same machine under a X11 session or it didn't crash on Wayland using Intel integrated graphics card.
