[Bug 250062] Re: [i945] partly corrupted screen after latest updates to Hardy [945GM]

I still get these issues in Jaunty.

Weird lines across the screen when scrolling, black bars also appear
when scrolling in certain applications. Seems that the addition of an
external monitor may cause this issue. I will test further and report
back.

xorg.conf is pretty simple.

/etc/X11/xorg.conf

Section "Screen"
	Identifier	"Configured Screen Device"
	Device	"Configured Video Device"
	SubSection "Display"
		Virtual	2048 768
	EndSubSection
EndSection

Section "Device"
	Identifier	"Configured Video Device"
EndSection
