what machine is this on, is it a directly connected monitor?

> what machine is this on, is it a directly connected monitor?

HP ProLiant ML110 G6
It has one VGA port.

Comment 6 Jérôme Glisse 2014-11-03 14:11:02 EST

So i witnessed the issue and it is a simple pitch issue (or maybe a 24bit/32bit issue as iirc mga is the crazy hw that can do 24bit framebuffer).

Comment 7 Adam Jackson 2015-07-15 16:27:03 EDT

Reassign to xorg-x11-server, which has replaced -modesetting in 7.2.

Comment 8 Adam Jackson 2015-07-22 12:33:26 EDT

Do we still see this in 7.2?

Comment 9 Adam Jackson 2016-07-20 10:25:52 EDT

This ought to be fixed in 7.3, but does need testing.

Comment 10 Adam Jackson 2016-08-17 15:56:48 EDT

New modesetting shadow code should have fixed this, moving to MODIFIED.
