Bug 430656

Application: plasmashell (5.20.4)

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.9.14-1-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

I have a new screen with HiDPI connected to my Thinkpad dock. I use Wayland for better HiDPI support. When I login to a Wayland (Full) Plasma Session, the plasmashell seems to crash immediatly and respans then successfully afterwards.

My session is configured to restore the previous session.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
