Can confirm this happens with the FLTK build on both M1 and Intel running Big Sur. Native UI version not affected.

Not familiar enough with FLTK to diagnose. Maybe it's not using the normal macOS runloop.

Upgrading my Mac as we speak... . I will take a look at that.

OK, I can repeat the problem. That's a good thing. The issue is the same on Intel machines. Thanks btw for the great description including video!

OK, this is a known issue with FLTK when building for older MacOS systems (I included 10.9 Mavericks). It is fixed now. There are now two FLTK versions fro MacOS:

Also updated build instructions.
