Bug#526257: libqtgui4: Possible reliable reproduction with window decorations

[Adam Spragg <adam@spra.gg>]

Package: libqtgui4
Version: 4.5.1-2
Severity: normal


I also get this quite a lot on my system. However, I can reliably get
the effects on the window borders with "slingshot"

If I load slingshot, the window decorations are fine. When I move the
window around the screen, the decorations (title bar and borders) are
completely corrupted, in the same manner as the other corruptions I see
with normal qt4 apps. If I hover the mouse over animated decorations
(close button, minimise button, etc...) then those elements repaint and
look fine. If the focus changes to another window, the decordations are
repainted, and all is OK.

slingshot is not a qt4 app, but given that the window decorations are
painted by kwin, which is, I figured this might be part of the same bug.

I am running slingshot-0.8.1-p2
