Unhappy Opengl based applications freeze when windows is selected.

Hello All,

I've got an odd issue that I've been trying to resolve ever since I've upgraded to Karmic.

This issue seems to occur within opengl-related apps such as glxgears and various second-life viewers.

When I go to select the opengl-related window, the application seems to freeze or halt. As soon as I select another
application such as gimp, firefox, chrome, etc, the opengl application starts running again.

I found rather than using the mouseclick to select the window, I can use my mouse-wheel to "scroll-select"
which seems to keep the app running, if I grab the window and move it slightly
it seems to unfreeze as well as (re)minimize.

My particular system is running in a triple-head mode, using two Nvidia GTX260's, with Xinerama turned on.

As a quick test, I downgraded to a single display, (turning off Xinerama) and noted that the issue seems
to disappear.

Has anyone seen anything like this?

System specs are as follows:

i7 Quad Core- 2.67 Ghz
(2) Nvidia GTX260's

X.Org X Server 1.6.4
Build Operating System: Linux 2.6.24-23-server i686 Ubuntu
Current Operating System: Linux motoko 2.6.31-15-generic
Nvidia Driver: 190.53. (NOTE: I've tried 185.18-31, 158.18-36, 190.42, etc)

I've included various files including a nvidia bug-report, the xorg.txt (xorg.conf) file etc.

Thank you for your time.

Still seeing these issues even though I've upgraded to 2.6.32-35 (Lucid) + Nvidia drivers 256.53 (32 bit) and Xorg-server 2:1.7.6-2ubuntu7.4
