Description
savage driver: 2.3.8 on Savage4 xorg-server: 1.17.1
On linux Gentoo
Enabling ShadowFB, even with NoAccel = true (which has other problems) and DRi disabled, will result in a corrupted display. Apparently the image is drawn with some kind of wrong offset/line size: the effect is that icons, moouse pointers seem drawn in pieces several times, becoming unreadable. The screen looks reactive, one can try to click, move the mouse.
