Description Martin Flöser 2012-05-04 10:06:59 UTC
Created attachment 70851 [details]
Shadows where a window had been

Steps to Reproduce:
1. use Oxygen window decoration
2. use Compositing
3. Verify that shadows are rendered
4. close window

Actual Result:
Shadows are still shown and are removed with next full screen repaint

Expected Result:
Shadows are removed together with the window

Noticed this problem after the many merges on May 03rd.

- kwin/gles, backend relevant?
- w/ or w/o altered vsync?
- closing animations?
- oxygen-settings / "window activity change" animated?
Comment 2 Martin Flöser 2012-05-05 09:13:41 UTC
Reproduced the issues with:
* Oxygen
* Aurorae
* OpenGL 1/2 (gles untested)

Problem cannot be reproduced with XRender!

As closing animation Fade is used (verified by using animation very slow).
Comment 3 Thomas Lübking 2012-05-05 13:29:56 UTC
can reproduce - it's likely either because wrong quads, wrong clipping or wrong copyToDeleted
gonna have a close look
