I have menu-bar-mode, toolbar-mode, scroll-bar-mode nil, and I use 1
frame in full screen.

I also tried to use tabs today. That's when I noticed the messagers,
because I started Emacs in LLDB to maybe get an impression where the
freezes come frame with tabs. (No luck so far.)

Don't know how tabs are implemented, maybe these are also some NS
widget/view?

This also appears when never using tabs in a session, BTW.

Thanks, I'll try that tomorrow.
