Description masterdany88 2015-12-08 05:37:44 UTC

I've activated Kwin effect called eye On Screen. I've deactivated Window Aperture effect.
Now When click on widget show desktop, or trigger showing desktop other way it trigger nice animation and show only desktop. Windows are hidden. It is ok. Problem become when i trigger this twice. once to start, and second while animation is still running.
I hides window, and I cannot display them again. I have to restart kwin effects (ctrl+F12).

Reproducible: Always

Steps to Reproduce:
1.Trigger eye On Screen effect
2.Trigger eye On Screen effect again while earlier animation of "eye on screen" is still running


Actual Results:  
I cannot see any window after that. No meter is maximalised or minimalised.

Expected Results:  
Windows should be visible after secon trigger of show desktop

Patch in https://git.reviewboard.kde.org/r/126277/ should hit 5.5.1, but it's a scripted effect, you can just patch the local file /usr/share/kwin/effects/kwin4_effect_eyeonscreen/contents/code/main.js
