Ok, seens I'm the only one with this problem...
I'm a programmer, so I need to compile things, almost all the time. Problem is, on KDE 4.0.0, when I activate "Desktop Effects" (composite manager) and start to compile something, everything slows down to a crawl. This does not happen with kompmgr (composite manager for kde 3.5.7), bling (for enlightenment), nor compiz/beryl.
So, what's wrong? Is there any way to implement a "exposeƩ"-like interface on kompmgr, so I could use it on my plain old KDE3 (which, by the way, is waaaay faster than KDE4)?
