           Summary: Window-Resize with kwin composition leads to huge
                    amounts of swap used
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: linuxhippy at gmail.com

When resizing windows running the kwin as composition manager in OpenGL mode, a
lot of swap is used and the performance degrades over time.
Its a fresh Fedora-13 installation, with an R200 class hardware.

Even turning composition off again, doesn't seem to free the memory.

The following "free" outputs were with ~30s resizing between each:
Swap:      2047992     286732    1761260
Swap:      2047992     687388    1360604                                     
Swap:      2047992    1034560                                               
Swap:      2047992    1254236     793756
Swap:      2047992    1479360     568632  (kwin composition already turned off
again)

Its disturbing because:
- Suspend to disk doesn't work or is very slow, because all the swap is already
used.
- System performance starts to degrade
