Since updating my r500(radeon X1600 in an iMac) to jglisse's kernel and DDX I am seeing strange 2D and 3D drawing corruption. It seems as if two triangles forming a quad do not touch each other properly and a small diagonal line is visible. Sometimes a grid between many quads forming a window can be seen too. This happens with Compiz enabled, but also with pure 2D.
I am attaching a few screenshots from 3D apps however, since the issue is better visible there.

This is a screenshot of glxgears. Some 2D GUI elements are also visible. Compiz was disabled. If you look carefully, you can see the diagonal lines in the GUI elements of the top and bottom menu bar.

The triangular structure of the geometry is clearly visible here.
This is a regression that occured when I switched from airlied's DDX+Kernel to jglisse's.
9bf2b46874ff4b59f79ba4d2984727ddf056496d fix this, reopen if this is not the case.
Works fine now, thank you!
