Default Losing desktop access on resolution change

Debian Sid 64bit / kernel 2.6.34 but problem seen also on 2.6.33
KDE 4.4.3, early versions too, composition or not does not make a difference
driver: 196.36.15 / 196.36.24 / 256.25 / 256.29

when a native ( like Unigine benchmarks ) or WINE app ( like The Witcher ) changes the resolution i get stuck on a black screen or with the wallpaper with the mouse cursor and keyboard working
sometimes after a quick switch to a VT via the keyboard and back will let the app to recover ok
but most of the time only a X zap via CTRL-ALT-Backspace helps

sometimes i get a kernel OOPS and i posted a log in the dedicated thread here: http://www.nvnews.net/vbulletin/showthread.php?t=151032 but i even saw this kind of OOPS at an earlier time than the time when i tested the resolution change so it might not be related

another thing worth mentioning, in Unigine Heaven for instance i get the black screen when i want to change the resolution but on The Witcher the resolution changes ok but when i exit the game i get stuck

attached the bug report after trying to change the resolution in Unigine Heaven 2.1, switched to a VT and killed it, switched back to a working desktop, run The Witcher, change res ok, play a bit, exited to only a mouse and a wallpaper and then killed the X server

This is still an issue with 256.44 too.

I've updated to KDE 4.4.5 and I've found out some more things in the mean time, if i kill kwin (i can switch to a VT) i can get back to the desktop (taskbar, systray, etc) but i can't run anything, if i have a console open i can start kwin& and get full functionality back.
