Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: dgls...@gmail.com

-- Information about the crash:
- What I was doing when the application crashed:
Rearanging icons on the desktop
- Unusual behavior I noticed:
Before the crash the icon that was being dragged didn't show the icon's graphic
next to the cursor.
- Custom settings of the application:
Plasmashell running on a 4K display, with the UI scalled to 150%
The crash can be reproduced sometimes.
-- Backtrace:
