I have been trying to use my second monitor with blender without much success.
I have 2 windows and can move them around fine, but the moment i move any window off my main screen onto my second monitor the blender interface window on the second monitor lags like crazy. But on the main monitor it is fine. I can also have both windows on the main screen fine without and lag.
It is driving me mad and while not necessary for what i am doing it would make my life much easier if i could use both monitors.
