Hello guys! This is a BIG problem I've been having recently after a much needed software update which included drivers for Intel's HD 4000 IGPU.
So, after spending quite a while searching for a solution (and messing with the driver's binaries; which, btw, don't) I found this:

TL; DR:
Latest intel drivers are bugged, downgrade to 9.17.10.2932 (December 2012) and be plagued by this problem no more.
