Description arne anka 2015-08-03 09:33:39 UTC 
debian/sid
xserver-xorg-video-radeon 1:7.5.0-1+b1

i got two screens with the same resolutions (albeit slightly different physical sizes).
both screens are configured to appear side-by-side, on one screen (left) a konsole window and a minimalist panel, on the other (right) a fully loaded panel, both panels set to auto hide.
since about last tuesday (debian/sid daily upgrade) after login both screens are merged:
- the same image appears on both displays
- both panels exist, the left (minimal) shows always, the right (full) appears on hover

Please attach the output of `kscreen-doctor -o` when the layout is set how you want, and then again after it gets messed up. Thanks!
