Hi Adam, I do have a testcase, I decode/render video with NVidia's
VDPAU constantly, over time the system becomes really sluggish, a
simple comand like "ls" will take about 30 sec to process. I have been
trying to find out what causes this, I run my application within
valgrind and it doesnt report any memory leak. Upon some searching
online , I found people going thru similar experience and it seemed to
be caused by glx, and still happens after doing an update to xserver
version 1.6.4 (thats how far I could go with ubuntu's repository
xorg-edgers). I did compile xserver 1.8.9 but I am not able to see
anything on the screen - perhaps nvidia kernel mode driver is not
compatible with it ..
