Description Ignat Semenov 2010-05-14 15:19:02 UTC 
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

With the new KWin blur effect enabled, the shadows of Plasma tooltips are blurred as well. This results in a large area instead of the shadow which is equally blurred (as in, the shadow should fade out nicely, and it does that without blur, but with this effect, it doesn't, it's just a large blurry area.) Obviously, the problem is that KWin blurs everything with the shadow, whereas it should only blur the area behind the tooltip and shouldn't touch the shadow. Don't know if this is a simple one, as I remember that communicating the right window shape to KWin is not that easy.

Yes, now I see that the blurred area is rectangular, whereas the tooltip is not. This seems to bring up the old discussion about how do we paint the shadow correctly with complex window shapes.

Using KDE Sc 4.5 RC5, I can confirm this bug. (Haven't the possibility to test RC3 or HEAD) - but it seems that the shadow is blurred as well - shouldn't that NOT be? the blurring should not extend the widget size, as it does.
But I don't have a glue what the underlying layers do ;-)
