-- Information about the crash:
Gridcoin (minimized to tray) and BOINC where running, like almost every
evening, when I locked the session, turned off my monitors, disabled my laptops
panel (DnD-Mode) and went to bed.
This morning I was greeted with the crash handler.
This never happened before upgrading to Plasma 5.27.0.
Main screen is a 2K screen at 144Hz. Secondary are my laptop panel and an extra
HDMI connected monitor, both in FHD.
xrandr information:

eDP-1-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis)
