Public bug reported:
Binary package hint: gnome
A strange thing happens to me in Gnome session after upgrading Maverick
to Natty.
After GDM login, I can't move windows completely off the first (left)
screen. They will only move so far such that about 100 px are still on
the left, then no further.
I can drag the bottom-left handle out to extend that side, but if I then
try to shrink to the second monitor's bounds using the bottom left
handle, the window immediately resizes to fullwidth (offset by those
100px or so), and continued dragging inwards of the lower left handle
causes the window to shrink, *but keep the same left edge*. So by
dragging the bottom left handle, it's the right side that moves left!
Maximizing a window centered on the right monitor maximizes it so that
it is partially on the left screen, with the far right of the right
monitor uncovered. Windows on left monitor maximize and moves fine.
Now the really weird thing. The only way I have found to workaround this
issue is to go into Monitors control panel -- and *change one of the
monitor's refresh rates.* I don't even know why this works. I can then
change it right back to where it was, in fact, it doesn't seem to matter
what I change it to or from, and the workaround stays.
