Description Kai Uwe Broulik 2011-03-08 11:15:47 UTC
Version:           unspecified (using KDE 4.6.1) 
OS:                Linux

When closing a window that has client side alpha channel shadows (e.g. Oxygen) you have a thick black border around the window. I don‘t know if this actually is the shadow (since I have black shadows which would match and I don‘t know if this border will be turkey/blue when using the default glow) but therer is a black border around the window that is being thrown against you.

Reproducible: Always
Comment 1 Martin Flöser 2011-03-18 19:26:35 UTC
no, there seems to be something fishy. I noticed during port to GLES.

Explosion is very high on my "to be removed" list, btw.
Comment 2 Kai Uwe Broulik 2011-03-18 19:30:22 UTC
I just reported it, not that I will ever going to be using this Epilepsy-causing effect :D

Screenshot under 4.9.0

The effect as well as its bug is still present in 4.9.0. ;-)
Personally I do not care for the effect. If you do not care to fix the bug, see my comment as friendly reminder to delete this effect fro 4.10 (or even 4.9.1/4.9.2 if rules allow it). :-)

PS, the usual for KWin reports:

Comment 4 rockonthemoonfm 2012-12-24 20:21:40 UTC
this bug is still present in KDE 4.10 RC1. (Intel SB, Kubuntu Raring)
at the same time, also this bug https://bugs.kde.org/show_bug.cgi?id=306376 is present.

I strongly suggest to remove this fancy effect before final release as it is plain broken and makes the desktop unusable.

The older bug is not a dupe of the newer. It's the other way around. ;-)

Comment 8 Thomas Lübking 2012-12-26 07:23:07 UTC
This is a report of a disfunction, the other is a collection of such in a task, explicitly created for that reason.

Please don't mess up my git history for stupid "i'm first" ego junk, thanks.

Comment 9 Thomas Lübking 2012-12-26 18:43:39 UTC
Sorry for the not so kind tone - you certainly had best intentions by ordering the bugs.
I'm just not very kind around christmas (turns me into grumpy smurf every year, i wake up being totally pissed ;-)

The reason for the inverse dupe order is that the "dupe" is actually none, but i just linked explosion effect related bugs to that collector so that by closing it with a dropping commit, they all get closed automatically.
In case the explosion effect would actually not get dropped, i'd of course have to dispatch (undupe / reopen) them again.
