3d windows glitch in compiz fusion

[graphixfx]

i am running compiz-fusion on SLED 11 and when i run 3d windows and move the cube around the windows get cut off to where only part of the window is showing
also when i change certain settings (i am not sure how to recreate this problem but it happens often with different things) in compiz fusion settings manager the desktop effects turns off and i have to turn them back on and everything works again (except for 3d windows) but this is only a temporary fix

Any help would be appreciated Thanks!

this very well may be a bug that should be posted into launchpad.

You can try this to see if it's compiz decorations that's causing the issue

Go into your compiz settings manager

find windows decorations

replace the compiz part in the entry spot with the following code:

emerald --replace

restart and then try the 3d windows. This way you can at least narrow things down

thanks for the reply

i replaced the windows decoration with emerald but it is still cutting off the windows
any thoughts on what to try next?

What hardware are you running? ie what video card?

its a lenovo ideapad s10e with a NVidia Quadro NVS 140M

okay sorry wrong graphics card its a lenovo ideapad s10e with a Intel Mobile 945gm/gms/gme 943/940gml Express Integrated Graphics Controller

See if the Intel driver is being used. The driver is defined in a file called
/etc/X11/xorg.conf

look for a section that looks l like this. The driver should be i810

Section “Device”
Identifier “Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller”
Driver “i810”
BusID “PCI:0:2:0”
EndSection

UPDATE
This may help but it contradicts the above driver name. It says use "intel" So I must admit I'm confused.

Intel Linux Graphics: Installation

okay i found the file and section and it said:
Section “Device”
Identifier “Intel”
Driver “i810”
BusID “PCI:0:2:0”
EndSection
should i change 'intel" to "Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller"?
i will try to use the link asap (i have limited internet acsses time becaue my internet at home is down atm) i will see if the link helps it might be a while though

Ok that appears right, I guess. This may be purely a hardware issue. Let's see what kind of frames per sec you have. Open a console/Konsole window and run
glxgears
This will show a neat graphic and report the Frames per second in the console.

The the timings are under 1000 FPS then either the hardware or the Intel driver simple is not up to the job of rendering heavy duty 3D. My NVIDIA 6800 card shows ~10,000 FPS. If the glxgears does not run there is no support for OpendGL ie 3D acceleration.

I've heard things about the intel driver being iffy with 3d rendering. But there is a new driver out...I know that the new version of Ubuntu runs it....

try changing "intel" in driver to "i810"

make sure to backup your xorg before doing any changes
