Sometimes when i do a extrude planar curve to make a solid my viewport, or rhino, responds extremely slow and allmost freezes. If there is a panel in the screen it starts to glitch in white. I have the same behaviour with pushing the alt-button and then using the gumball to make and move a copy.
I hav a holomarkscore of 63225 and an nvidia quadro k2200 on win 10 64 bits. Rhino is up to date and the fiel is not extremely big.
What could be causing this?
