Description S. Christian Collins 2009-09-26 00:43:05 UTC
Version:            (using KDE 4.3.1)
OS:                Linux
Installed from:    Ubuntu Packages

* Bug Description *
When a plasma notification or pop-up (such as when hovering the mouse over taskbar entries) appears, it will sometimes create a "hole" in a window elsewhere on the screen.  The "hole" appears as a section the size of the notification/pop-up cut out of a window (in other words, you can see the wallpaper through it).  The hole will remain there until something causes it to redraw that section of the screen.  It's kind-of hard to explain the appearance of this bug, so in lieu of a thousand words, please see the screenshot.

* Reproduction *
I have yet to be able to reproduce this with any kind of consistency; it seems to happen rather randomly.  The only thing I know for sure is that it does not happen with desktop effects enabled.

* Other Notes *
The screenshot has been manufactured, since I have been unable to capture this phenomenon in action.

This is an old X.org bug: bug 177959 / bug 173686.
Thanks

This is clearly a Xorg bug, I was able to write a xlib-only testcas (as I was asked for), but then nothing happend.
