New Floating Viewport Issue

I have to external Screen/monitor connected via Display Port on a GTX 1080 with the latest version.
I am running Rhino 5 sr14 on Windows 10 Pro.
Every time i need to “newfloatingviewport” on second monitor to maximize viewport that floating viewport start flickering. Impossible to get the viewport fixed a stacked there.
Is any one with this issue?

Hello - so, is this correct-

  • you run newFloatingViewport and then maximize the new viewport on a second monitor.
    -the new viewport flickers.
  • it does not flicker if it is not maximized…



It flickers every time i draw on rhino normal window. Some times floating viewport disapear
