Target Milestone: ---
Application: kwin_x11 (5.12.2)
(Compiled from sources)
Qt Version: 5.9.4
Frameworks Version: 5.43.0
Operating System: Linux 4.12.5-jchlb-0a5d70d3a6ac x86_64

Moving a window
- Unusual behavior I noticed:
I just upgraded KDE. Since the upgrade, I noticed that there are strange video
