Driver dilemma in KDE workspaces 4.5

"KDE is currently blamed for errors in external components: the graphic drivers. I am lately reading quite some crap (e.g. on it news today) that we KWin devs knew about problems in the drivers and shipped 4.5 nevertheless with changes enabled which trigger the driver bugs. That is of course not true.

"First let's have a look on the checks KWin performs in desktop effects:

* Desktop effects are only enabled if the driver is on a whitelist of known working drivers
* The capabilities of the driver are verified by an external helper application
* If KWin crashes while initializing the driver (you have to access OpenGL to know if OpenGL is supported), KWin will not try to enable desktop effects again
* If KWin crashes twice in a row (not during driver initialization), desktop effects get disabled to prevent further crashes"
