This has happened several times today. I seem to get rid of it by recompiling a script, or restarting the editor. I can’t reproduce it, it just seems to happen when I switch back and forth between unity and something else.
It looks like some letters are missing, like “am” in X Damping on the right, and “oo” and “ea” in Lookahead, in the CM virtual cam.
I’m using Mac Os Mojave (10.14.4) and Unity 2019.2.5f1. I just switched to this version a few days ago.
Yep, happening to me after upgrading too 2019.2.6f1 with Mojave. I have to minimise Unity, show it again and then click into it before the text is restored.
