Xcomposite, аnd many the "heavy" open windows

[Andrew Muhametshin]

Greetings to all!

1. We start the X compositing. ("kompmgr -a" or  "xcompmgr -a")
2. We open many "heavy" windows - 5-6 or more. (mozilla, Konqueror, 
Konsole, thuderbird, Kate, etc.)
3. All works perfectly! -- until then while any of windows to not 
minimize on the taskbar. (In a window should be, any, contained, that 
there would be a scrollbar)
4. And so! After restoration of the minimized window, scrolling of its 
contents works very slowly.

Whether it is possible to eliminate this problem?
