Black flickering

Hello
After I play a game in full screen mode (using openGL) I get black flickering on screen.
If I e.G. move a window around or start to play a video the video window is normal but every other area of my screen turned black or flickering black.
If I press on an other window everything went okay.
Something todo with video buffer?
I have a Nvidia GeForce 1050 Graphic card.
Last 430.xx driver installed.
