Public bug reported:

I use a dual monitor configuration (with merged framebuffer) with an ATI
adapter (ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]).

I use the open source radeon drivers (with R300 acceleration).
glxinfo gives this (among the other information): "OpenGL renderer string: Mesa DRI R300 20040924 AGP 8x TCL"

I'm using kubuntu dapper (6.06.1).

The first screen is set at 1600x1200, while the second one is at
1280x1024, thus the total horizontal resolution is 1600+1280=2880.

I know the 3d acceleration on this card do not support the whole area,
part of the second screen is not working with 3d graphics.

When an opengl screen saver starts (kscreensaver), I see garbage on the uncovered area.
With Ubuntu Breezy (gnome), however, that same area was blanked (=kept black).

It happens with almost all the opengl screen savers, currently, however,
I'm using keuphoria.

** Affects: kdeartwork (Ubuntu)

         Status: Unconfirmed
