Hello,

Following https://bugs.kde.org/show_bug.cgi?id=356740 , when I’m in Kodi and I increase/decrease brighness the screen flickers because the taskbar show up briefly.
I got no problem when increasing/decreasing audio volume.
On the other bug this was said:
«The reason will be that the indicator is not override_redirect and does not refuse focus, so it gets activated and the netwm spec requires fullscreen windows to shift back to the normal layer when they loose the focus (desired behavior because otherwise the active window would not get in sight). This implicitly drops them below panels (and some other windows) as well.»

Reproducible: Always

Steps to Reproduce:
1. Open Kodi (or most likely any fullscreen app)
2. Increase or decrease brightness


Actual Results:  
The taskbar show up, sometimes other windows/indicators as well, for a brief moment.
When increasing several times it flickers between this and kodi.

Expected Results:  
Only the brightness indicator above Kodi, no flickering and no taskbar.
