This worked before. I believe it worked in 3.14. It definitely works in 3.11-rc2.
Screenshot or more detailed description of what "only top 20% of screen works in X" means?
Well, top cca 20% is ok, then I got repeated pattern of some part of screen.
Anything in dmesg?
That will take a look.
bisect result presuming that it reproduces reliably?
If there's no other chance, I guess I could do bisect. But first.... Do you have similar hardware? Does it work for you? Are there any experimental changes that went in recently and I should try reverting first?
