I’m encountering a strange issue with Grasshopper in Rhino. Occasionally, after I close the Grasshopper window, a transparent ghost window titled “Grasshopper - unnamed” remains stuck at the top of my desktop screen. It doesn’t respond to clicks or keyboard input and stays visible until I restart my system.
Here’s a screenshot showing the issue:
Rhino Version 8 SR23
Windows 11 Pro
GPU : NVIDIA GeForce RTX 4070
Note:
The issue doesn’t happen every time, but when it does, the only fix is a full system restart.
