SW3D 6.1.2
Linux Mint 19 x64

When I attempt to display my model 3D in a separate window that window is blank. Flipping back to normal view works fine.

Creating a new model works in the separate window. Opening an old one doesn't.

I have 3 monitors but am forced to use only one, which is somewhat annoying.

Any ideas?
