In the latest versions of GS CurveTools there was a change to how UV Editor is rendered. It now uses GPU acceleration.
However, I now receive some feedback that on some configurations this leads to problems with Maya viewport when using UV Editor. Maya Viewport might turn black, or some other artifacts might appear. I'm investigating this right now.
If you have any issues, try disabling OpenGL acceleration in GS CurveTools -> Options -> Settings -> Use OpenGL in UV Editor. Press Save button and restart Maya.
I would love to hear your feedback via comment here, email or on my discord server.
This issue can happen to Maya versions up to 2025. In 2025 and 2026 there was a major change that eliminates this issue completely. I will see if this can be fixed, if not I will revert this change and make OpenGL disabled by default on those older Maya versions. Stay tuned.
