White screenshots

[Radament]

so far i havnt experienced getting "white" screenshots upon making them, however from time to time my MH window does shortly flashes into a white screen, but not when doing screenshots, sadly i cant really tell how to fix it besides trying different approaches upon making screenshots like:
1: print screen (normal screen capturing).
2: Alt + print screen (of MH window) then Ctrl + V into an image editor. (like a copy/paste method).
3: use the browser tool puush or similar tools when making screenshots.
