Description Daniel Berrangé 2008-03-20 21:04:48 UTC
Description of problem:
I'm running 

   xcompmgr -n -f -c -C

In my regular GNOME session. After a couple of hours of desktop usage xrestop
shows it has  650 MB of pixmaps allocated on the X server

res-base Wins  GCs Fnts Pxms Misc   Pxm mem  Other   Total   PID Identifier    
0600000     1    1    0  285 17763   649297K    416K 649713K   ?   xcompmgr

this appears to be continuing to go up consuming all my RAM pushing other apps
into Swap. It is unclear whether this is a 'leak' or just over aggressive
caching - if the latter it needs to purge things a bit more often.

If I kill xcompmgr all pixmaps are freed.



Version-Release number of selected component (if applicable):
xcompmgr-1.1.3-7.fc8
xorg-x11-server-Xorg-1.3.0.0-42.fc8

How reproducible:
Always

Steps to Reproduce:
1. Run xcompmgr -n -f -c -C
2. Use desktop for 2 hours
3.
  
Actual results:
X is using huge amounts of memory for pixmaps for xcompmgr client

Expected results:
A 'reasonable' amount of memory is used - where 'reasonable' < ALL RAM.

Additional info:
In case it is relevant, the machine has a r500 graphics card, and is using the
open source ATI driver from the  r3xx-render branch. 

It doesn't appear to be driver specific though, because another machine with
Nvidia driver is showing similar levels of pixmap / RAM usage.
