I changed the specified line to

Is this bug fixed in 3.5.0 from the above SVN commit 414884?  This still happens in FC3 using KDE-Redhat RPMs of 3.5.0.  Here's what I've witnessed.

kompmgr, started fresh, takes about 15M of ram.  I can play some games, browse the web, flip desktops, use mplayer, etc, and it stays around 15M, no problem.  Then overnight it balloons to 270M.  I don't have any screensaver, it's completely disabled.  I have DPMS set to turn off the monitor.

Not sure of my exact settings right now (at work), but I just have transparency on, no fading, not sure about shadows offhand.

If there's more information to give, let me know what/how to provide it and I will.  If this seems like a separate bug I file a new one.

Change not yet incorporated into Kubuntu (KDE Desktop apt package for Ubuntu).

This appears to *not* have been fixed as of KDE 3.5.3! The original change appears to be the correct fix.

Comment 6 Lubos Lunak 2006-12-13 20:13:27 UTC 
I've fixed some more leaks and I cannot reproduce any more problems.
