When I switch users or switch between for example the x2go application in full screen (which displays an X11 desktop) and the windows desktop or basically anything that "resets" the screen, about 20% of the time the new screen appears with the right upper and lower left and right quadrants of the screen solid black.
The mouse can still move over the black parts and the respective portions of the windows of the open applications are still there -- it is just as if this part of the screen is "blacked out." The upper left quadrant still shows its quarter of the desktop properly and the scale is unchanged. Interestingly the only thing that displays in the black portions is the mouse cursor when it is moved into the blacked out region the screen.
The only way to get the entire desktop to appear again is to switch users and hope when the screen resets that the black part goes away, which it usually (but not always) does on the first or second try.
This problem did not occur with my earlier driver (pre 4300) but there were flickering problems when returning from standby that prompted me to upgrade.

(unfortunately when the screenshot is taken the portions that are black on the physical screen are not black in the screenshot that gets captured ... which looks how the screen should appear)...
