Hi there!
I created a new issue on Godot’s issue tracker, but it may well be a NoMachine issue, hence this blog post.
Here’s the link: https://github.com/godotengine/godot/issues/91839
Just to summarize, middle mouse drag does work on Firefox, but doesn’t on the Godot Editor, which severely impacts my ability to develop the program remotely on my new Mac mini.
I tested connecting using [removed] with macOS builtin remote screen access, and middle mouse dragging worked flawlessly.
A video and more details are available following the link above.
Thank you! Great software by the way.
