Since 14291 rs1 160314-2254 installed using Snip (not Snipping Tool) causes windows to move stuff between my three monitors (on two nVidea 750Ti cards). Running a video player Daum Potplayer 64bit causes all screens to flash but only if run full screen. In addition a window on an MS site has a very strange foreign looking font in the text labels

I've rolled back the NVidia driver from 364.47 to 353.30 to no effect and also removed all other NVidia utilities.
