Re: Gimp causes 100% processor load

The problem is indeed strange. I have a similar problem with Firefox (SuSE
8.2), wherein I suspect that the cause might be plug-in collisions. In
fact, many plug-ins (extensions) are known to intervene with each other and
cause problems under certain circumstances. Much like you say, I have
Firefox surging to ~70% and the rest is devoured by X.

So, I suppose my point would be: are you installing some additional software
or plug-ins to the GIMP? Have you tried installing GIMP 1.2 to see if that
makes a difference? A live CD? The behaviour is really difficult to debug.
Regressing which discovers a state/s which still work/s helps in
identifying the source of the problem.

Are you forced to quit the GIMP after that obscene CPU load? Does the
problem fix itself? In my case, I get 'warning signs' before the CPU usage
climbs on and on. So, I have plenty of time to save my work and then quit
(restart). It is a pain due to tabbed browsing and I am sure it is too when
you have palettes, layers and multiple images open.

Hope it helps,
