please see https://jogamp.org/bugzilla/show_bug.cgi?id=1398 
this bug, that all mac os x window updates must be done on the main thread, is one of the current release blockers for jogamp jogl 2.4

the latest change to fix this issue was added 2020-06-15 01:21:44

i do not think we have a test build that include the very last fixes. you may need to try compile jogl if the last testbuild do not solve your issue.
