problem of Mesa drawing boxes after resume from suspend with Geforce4 420 Go
When it has finished to boot everything works correctly: I can move the Pidgin window or I can lock the screen: boxes are drawn correctly. Yet after resume from s2ram/suspend you can see a black box as the background of the status bar tray instead of a filled one, moving pidgin leads to box-shaped screen distortions and the background box of the login dialogue is not drawn any more. Using Mesa patches from Karol Herbst for gtk3 apps (#174); xscreensaver as well as the drawing of the lxde status tray bar shall be independent from this however (non-gtk). Same issue with suspend to disk.
