Rhino 8 Mac SLOW with external monitor

Here’s a clip of what the behavior looks like.

It’s only related to “Edit” type behavior:

  • Drawing a 2D line, the display of the line lags behind the cursor.
  • Panning a simple 3D shape in perspective view is realtime/snappy.
  • Resizing the viewport-panes is laggy.

I run the screen at 1.25 scaling (So I run at “2048x2034” for 2560x2880 native resolution).

It looks like when the Rhino window is set smaller (even on the scaled screen), the issue doesn’t exist or isn’t as pronounced.

I can work with this – I hope it’s able to be addressed at some point.

Let me know if there’s anything else I can do (Including post on the bug report) to help resolve this!
