Package: xorg
Version: 1:7.5+8
Severity: important

Since the upgrade to squeeze from lenny, I have an issue with
some applications instead of hiding the mouse cursor after a
second or so, going into a high CPU flicker. This flicker
persists as long as the mouse cursor is over the window and
stops if it is moved out of it. For example with geeqie, I
get 66% load for the app and 66% load for xorg (quad core system).
I see the same effect also in libreoffice (not debian package),
and amulegui (debian package). The affected applications            
basically become unusable.

This sugests to me that this is an xorg package problem, or
possible a toolkit problem. Since I was unable to identify
what package exactly causes the issue, I am filing this against
the xorg base package.

Graphics driver is "radeon" with a HD4850. Mouse driver
is  "ImPS/2". The problem is also present with
the "radeonhd" and the "vesa" driver, which suggests
it is not a video-driver issue.

I tried to identify common dynamic libraries in all the
three apps:

      3         libc.so.6 
      3         libdl.so.2
      3         libfreetype.so.6
      3         libgcc_s.so.1  
      3         libm.so.6      
      3         libpthread.so.0
      3         libstdc++.so.6
      3         libX11.so.6
      3         libXau.so.6  
      3         libxcb.so.1  
      3         libXdmcp.so.6
      3         libXext.so.6   
      3         libz.so.1      
      3         linux-gate.so.1

It is possible that the problem is in one of these libraries.

Extensive googeling for the issue did not turn up anything,        
except that some video drivers seem to have had similar issues
in the past.

If there are any specific experiments I can run to help
tracking this down, I would be happy to do so.

Please use the reportbug tool when filing bugs, it includes a lot of
important information that was missing from your report.  I'm closing
this bug for now, but if it's still an issue please make sure to:
- install the relevant firmware package for your radeon (should be
  firmware-linux-nonfree) and reboot
- if that doesn't fix it, include the dmesg and X log from the machine,
  and any profiling information you can gather about where the CPU time
  is being spent.

Cheers,
Julien
