Problem with the new xf86-video-vesa(2.4.0-2) it might be linked to xf86-video-fbdev(0.4.4+13+g9af7f81-1), xorg-server(1.20.0-2) and xorg-server-commen(1.20.0-2)

Unable to rotate screen without it turning black, only able to see the mouse courser nothing else, function fine in normal mode. also lots of flickering if a second screen is attach during startup the flickering will stop after some time.

Distro: Arch Linux
failing xorg-server package: xorg-server-1.20.0-2
working xorg-server package: xorg-server-1.19.6+13+gd0d1a694f-2

I have experienced a similar issue running with the xf86-video-ati driver. The second (and only rotated) screen is constantly flickering whenever there is a redraw and is often completely distorted and flickering so little is readable. 

I find that the flickering does stop/slow down when the cursor is not moving, and nothing on the screen is being updated.

Reverting to the last working xorg-server package and everything works fine again. Note that the same version of xf86-video-ati is being used, though compiled with the matching xorg-server version.

I'll attach my log file, though I doubt it has anything useful other than version info.

Please file your own report against the radeon driver, and also include the output of

 xrandr --verbose

while the problem is occurring.
