Description Max Schettler 2016-03-15 09:17:26 UTC

When using the task switcher (tested with breeze and thumbnails), the visual highlighting is only displayed for every second selected window.

Reproducible: Always

Steps to Reproduce:
1. Open at least two windows
2. Use the task switcher to cicle through them

Actual Results:  
Every second window is highlighted when currently selected.

Expected Results:  
The highlight should be shown for every window

> OpenGL platform interface: EGL

*Very* likely a dupe of bug #338150

Please check whether it also happens when switching to GLX in "kcmshell5 kwincompositing" and see https://bugs.kde.org/show_bug.cgi?id=338150#c10

Comment 5 Max Schettler 2016-03-15 10:45:12 UTC

Switching to GLX fixed the issue. I also stumbled upon the bug report you posted for a different reason, unfortunatly I cannot use DRI3 because of a bug in SDDM.
