Description rockonthemoonfm 2013-07-17 16:16:20 UTC

bug not present in 4.10, regression probably introduced with indicator glow style and fade-out effect

Reproducible: Always

Steps to Reproduce:

1. de-activate translucent window while moving effect to better see bad behavior 
2. pick a window with dark background (ex. konsole) to better see bad behavior 
3. drag it to a side border for quick tiling
4. untrigger quick tile effect
Actual Results:  
when quick tile indicator fades out, window background flashes

Expected Results:  
no flash, smooth indicator fade out in background

Comment 1 Thomas Lübking 2013-07-17 19:16:11 UTC

This is because the window is immediately un-elevated, dropping behind the indicator and - since the air theme is translucently bright filled - you see the konsole window lit by the (fading) indicator in front?

definitely yes.

set effect animation to "very slow" and saw it clearly: tile indicator fades in front of window.

Comment 3 Thomas Lübking 2016-01-30 14:02:40 UTC

essentially the same bug: we need to get rid of the requirement to elevate the dragged client, the this bug disappears implicitly.
