I see the same issue here. I will try to place some of the info.

Fullscreening/unfullscreening a couple of times usually brings most 
of the picture back. Or as described, resizing or moving the window
brings this up sometimes. It is not reproducible like every time, but I
need normally less than 5 fullscreen/unfullscreen to show it - and 10-15
to make it go away again.

mga_vid module is r254 - I have tried r251 also. it seems to have the
same flaw, but not quite as often.

I don't remember when it started to appear, but at least around kernel
2.6.16, I don't think I saw it.


I have tried insmod'ing it with different values of mga_ram_size (as
some mplayer faq suggests this), but it doesn't seem to make much
difference.


Any other information needed? or specific tests I should do ?

You neither should ever unlink the login, nor must digit on a ROM e-mail of 
the POPmail kernel to a 2X 2D front-side bus over a head on a Internet site
