I think it is due to b777b51147e7b9ea0d89d480273d4d8240c9b594

tools select, measure etc are also affected !

Can not replicate on Mac. The marquee on mouse drag is still transparent here.

Hi Larry,
could you test Measure Line tool too ? or Select Features by Rectangle ?

In the video what happen to me!

Hi Salvatore,

Same thing, no issues. Not seeing the greyed-out fill like in your video.

The Measure Line dialog now gets sent to behind main window (in window stacking order) on measure tool's second click, but that's a different bug.

confirmed here on LinuxMint with fresh master (11.Dec.2012)
Strange behavior detected:
measuring tool (angle): it is dependant if is start top-down (nothing happens) or bottom-up (every 2-3 try the screen gets completely grey)
measuring tool (line): I cannot see any line drawn any more. Line is not visible (if there is any)
Zoom: in or out - always getting a grey rectangle like in the png from Salvatore
Select Feature (rectangle): Also getting grey rectangle but not every time .. sometimes it is transparent again.. and sometimes it is transparent with a thick grey border .. unfortunately the amount of tries to get it transparent is unpredictable and therefore not reproduceable
Also selecting by polygon, freehand or radius is producing a non transparent grey rectangle.
