Description

Have a Radeon HD6450. Two monitors, one is anlog (SVGA?), the other DVI. Both displaying 1600x1200.

Both of them show the Haiku display. The SVGA has a some image 'noise' whenever anything is moving on the screen. Such as dragging the mouse, or (especially bad) running 'GLTeapot'.

The DVI monitor has some 'noise' all the time - even when there is no movement on the screen. But when there is movement, the noise is 10x worse than that seen on the analog screen.

Attaching an image of what the SVGA monitor is showing when moving the mouse around.

In my setup (hrev49169) running on DVI at 1920x1200,32bpp,60Hz, I can fix the hash by switching to 56Hz (causing a blank screen) temporarily. When 60Hz is restored the hash is gone. No idea what is going on.
