Hi,

We've got an inhouse software that opens up multiple windows as needed, it works fine with older version of kwin ( v0.95, which comes with rh9, ES3 , etc ). I can open 50+ windows, and it's fine. But if I try to run or display the software on a box running ES4 ( kwin v3.0 ), the more windows I opens, the longer it takes, eventually, after 18-19 windows, it starts taking 4-5 seconds to open a window. During that delay, kdeinit: kwin is taking up 100% of the cpu and won't process any wm events like mouse clicks. the more you try to open, the longer the delay.

Now, I can open 20 firefox windows and 20 konsole windows and it's fine. Something in kwin has changed drammaticaly, and it's not liking what our software is trying to do... not sure what...

Anyone has a an idea ?

Thanks
