I am using 3 screen setup, with MSI GE70 (GeForce GTX 766M), Windows 8.1.
When opening “child” window (for example with material nodes) everything is fine until it is maximized. When maximized “child” window when being refreshed makes “main” window flicker (it looks like it’s trying to paint “childs” window content in “main” window for a brief second).
I have latest drivers from Nvidia and I realize it might be this laptop specific problem (not first), but decided to mention it anyway.
Edit:
It was meant to be posted in “bug reports”. Sorry for the mistake.
