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

Hello!

I am new to processing and just learn the basics. I’ve encountered strange problem with initializing P3D. Launching 3d sketch takes almost a minute (p2d launches in a few seconds) + puts this in terminal:

java[51277:2217989] WARNING: NSWindow drag regions should only be invalidated on the Main Thread! This will throw an exception in the future. Called from (

Terminal will be reused by tasks, press any key to close it.

Have no idea what’s wrong with my system and how to avoid this.

MacOS, Catalina 10.15.4, mbp 2018, everything latest.
