Graphical glitches on GM965 since 2.6.37-rc1

[Brian Rogers]

Since 2.6.37-rc1, I see graphical glitches on various UI widgets. This can show as any of the following:

- a black rectangle around the URL bar in Firefox
- slightly glitchy scrollbars in various programs (most noticeably Konsole)
- a lot of graphical corruption occasionally covers the document list and toolbar in Kate

None of these effects are always there. They come and go. Overall, KDE applications seem to be more affected, and the problem is only severe with Compiz running. Without Compiz, the glitches are rarer and less obvious. Stability seems unaffected by the glitches, and 3D works without problems or glitches.

This problem doesn't exist with 2.6.36.
