            Bug ID: 425390
           Summary: Dolphin crashes upon moving to second monitor
           Product: dolphin
           Version: 20.04.3
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: krueglingzter at gmx.com
                CC: kfm-devel at kde.org
  Target Milestone: ---

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
