Comment 28 for bug 321224

Confirmed here on x86_64 with nvidia 180.29 and GeForce Go 7600.

I run dual-screen with separate X sessions. The primary (screen 0) exhibits the horizontal pixel-offset/wraparound and sometimes corrupted top 1 or 2 rows too (1280x800x24).

Adjusting the GPU Scaling momentarily seems to solve the offset, which suggests the driver is incorrectly initialising the device.

The secondary screen (1280x1024x24) positioning is fine *but* when the mouse is moved from it to the primary screen, an image of the mouse cursor remains on the edge of the screen whilst the cursor continues moving on the primary screen.
