I would like to add that I've only noticed the problem when DVI/DP cables are used to connect the external monitor. VGA cable works just fine. I have a Lenovo T520 with these graphics:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [Quadro NVS 4200M] (rev a1)

and two external monitors, the one connected with VGA works just fine but the second one connected with DVI has artifacts and rendering issues. A fix or workaround is very much appreciated.
