            Bug ID: 364019
           Summary: Screen is flickering when setting brightness while in
                    Kodi
           Product: Powerdevil
           Version: 5.6.4
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: plasma-devel at kde.org
          Reporter: come at chilliet.eu

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.
