X goes to 100% CPU on closing or iconifying windows

[Enrico Zini <zinie@cs.unibo.it>]

Hello.

I've setup a desktop system for dad and mom.  The box is not too
powerful (a K6II-400 with 128Mb of ram) but with a good swap partition
it should be usable enough for a desktop system.

The box is a debian testing with OpenOffice, Nautilus and the rest of
Gnome 2.  Everythig goes more or less smooth (once OpenOffice has taken
his 1 minute to load), except when closing or iconifying a window.

In that case, after pressing the WM button, X goes to 100% CPU for about
5 seconds, then the window disappears as it should.  No disk activity,
only CPU.  I verified with top running on an X terminal: the process
hung on the CPU is X).

I thought it could be an hardware problem of the old PCI S3 video board,
and I replaced it with an AGP ATI rage 128, with 32Mb of onboard memory.
Things are smoother, but the 5secs delay on window iconifying or closing
with X jumping on 100% CPU remains.

Do you have an idea of what this could be?


Bye,

Enrico
