I have this problem with MS Whiteboard w/ Win 10 fully updated, graphics-driver updated, etc. etc. The screen flickers whenever drawing (any color) on the whiteboard with my Mouse or pen. Most annoying.
I did, however, discover a workaround:
- Bring up an entirely black, full-screen image or background (on both screens if you have dual-monitors).
- Then place Whiteboard in one of the screens without covering the entire screen (i.e., not full screen mode), so that the black background shows around Whiteboard.
- Now draw using your mouse or pen and the flickering will go away.
So far (2 days in), the Whiteboard ink drawing works w/o flickering until I reboot, at which point I have to repeat the black screen steps above.
Would love if anyone w/ technical knowledge could explain why this happens. Meanwhile, I hope this helps other distressed users.
