NSWindow drag regions should only be invalidated on the Main Thread! #5

This is expected on macOS 10.14+ (since 2018). It's only an issue if you use OpenFrames' built-in window manager (via OSG). It is not an issue if using your own window manager, e.g. wxWidgets, Qt, etc, since those do event handling in the main thread. However, it should not be happening in the PyQt demo ( |

Don't know if this helps, but here is the full script that can be used to reproduce the problem: #!/bin/bash

Looks like this same issue has affected other OpenGL applications: Examples:
Seems to have been caused by something apple changed (maybe in macOS 10.15 or so?) |

Can we do a similar thing when using from Python? |

On an Apple M1 Mac (MacOS Ventura 13.1, clang 14.0.0), I can't get the examples to work.
For example, when running
ofconesI get:If I run
ofqt_demo.pyI get a similar error (-[NSOpenGLContext setView:] must be called from the main thread.)I'm compiling it with the following script (using conda for all the dependencies):
