[Bug 89845] Moving window hits barrier with kwin and xinerama

[Yann Neveu]

Public bug reported:

Binary package hint: kdebase

I permit myself to copy bug description from
http://www.linuxquestions.org/questions//showthread.php?t=526849

I have exactly the same problem with i810 driver and things work with
another windows manager (xfce one).

I have recently installed kubuntu 6.10 on a HP nx6320 laptop. I have
setup xinerama to use an external monitor as an extension of the desktop
(I have successfully set this up before on gentoo on other hardware)

I am running a kde desktop and have both screens active. I can move a
window from the primary to the secondary screen but the window seems to
hit a barrier part way across the other screen. The mouse can be moved
to the far side of the other screen, but not the window.

If I maximize the window when it is mostly on the secondary screen it
then fills the screen and seems to work OK.

Another thing is that the other screen's background (which is just set
to a solid colour) gets erased to black as the window is moved over it.

If I run X and ktwm it all seems to work fine so this looks like a KDE
problem.

I have seen a few reports of similar problems on the net but have yet to
see an answer to the problem. Any one have any ideas about this?
