Hello,

currently im using xserver 1.4.2 because since 1.5 i have a problem with
my setup.
I am using Xinerama with three monitors/2 cards which are rotated 90
degrees (Option "Rotate" "left") by the binary nvidia driver.
Everything works fine in 1.4.2. But in 1.5 i can see the following
problem (i tried to make a screenshot but it wasn't visible there).

If i start twm for example every window has a 1 pixel border drawn
around it. With 1.5 this border isn't there (visible) on startup. After
moving around the window it appears. If i drag that window onto another
so that they overlap and then drag it away again, i can see the contents
of that dragged window remaining in the border of the other.
The same effect happens with the twm menu.
This error only appears on the window borders and nowhere else.
Without Xinerama it disappears.
I tried several nvidia version, driver settings and xserver (1.5, 1.6).
Nothing helped except switching back to 1.4 again.

I've put some system info below, if you need more details please don't
hesitate to ask me.

Regards,

Jochen
