Description Alexander Hunziker 2009-04-15 13:16:51 UTC
When I enable the option "DynamicPM" in a snapshot from April 15, I get screen corruption. This happens on a Mobility Radeon X1400 on a Thinkpad T60 with a 1400x1050 panel.

What happens is that the picture is streched so that it is too wide, and it looks like two pictures are laid over each other, slightly shifted horizontally. I see this behaviour not only in X mode, but also when I switch to a terminal.

I have also corruption on my X2300 based laptop, using DynamicPM, 
and latest driver code. The corruption affects the mouse cursor and widgets.
I can't see any corruption when switching to terminal, like #1 commenter said,
and no stretching using 1280x800 resolution.

This should fix the corruption for the time being.  I'm working on a better fix.

Should be fixed now in git.
Comment 4 Papadakos Panagiotis 2009-04-17 09:59:37 UTC
Seems to be fixed here! Thanks.
