Broken: 2.79 and 2.80 dailies (guess the official builds as well)
Worked: Previous OS's
Short description of error
On OSX Mojave and HiDPI screen (iMac 2015 5k) interface is scaled wrong (way too large)
Exact steps for others to reproduce the error
Installed OSX Mojave.
Compiled blender (2.79 and 2.80)
Opening Blender shows an unreadable interface. You can barely see some buttons (all very large)
It's not corrupted.. just extremely large.
Pressing OSX "Full Screen" button or starting in OSX "Low Resolution Mode" fixes it temporarily.. but saving settings not.
I think the doubling of the interface on HiDPI now has to be scaled 50% or something.. My guess is that everything is 4x too large
Thanks for looking into it..
I'm back on Sierra.. btw ;-)
