Great it worked for selimrecep and Erwin, but it didn't for me, I updated (against the Tablet's (Microsoft's) advice) to Intel graphics driver 27.20.100.9168. Is that the same one that fixed it for you two? I had previously updated driver/firmware on windows update to 17763_20.020.2886.0. My issue only happens with whiteboard and as others have pointed out, only when using solid not rainbow colours - was that the same for you?
I also have had screen brightness flitting whilst the auto-adjust brightness was set - so have had to disable that.
I am not sure which version I have, but I can check in the night.
I just went to the intel website, click download drivers and there was a program that did all the detection and such... I only installed the new graphic drivers, not the other 2 options.
