Description Benjamin Hiebert 2020-08-15 16:22:41 UTC
Application: dolphin (20.04.3)

Qt Version: 5.15.0
Frameworks Version: 5.73.0
Operating System: Linux 5.8.1-2.g553537d-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
I started wayland using the option "Plasma (Full Wayland)" and I noticed that Dolphin would crash almost instantly upon dragging to another monitor. Moving around on one monitor is fine and everything else works from what i can tell, but it just crashes when moving to my secondary monitor.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted

This appears to be a crash in QtWayland, not Dolphin itself. Please report the bug there if the issue persists. Thanks :)
