Same here on a M1 machine. Very annoying during development.

Thank you for your answer. [quote='807092022, DTS Engineer, /thread/764006?answerId=807092022#807092022'] So, my main advice here is to rewrite things so that you stop doing this. It might be possible to get this working (see below) [/quote] I do not find anything below you referred to. Can you please advise? Thanks and regards Markus

Kevin, first of all, thank you very much for coming back to my question again. Only one last question: What do you mean by AppKit runloop modes? Are they accessible in a Catalyst environment? Thanks Markus
