Hi,
Yes, unfortunately Apple’s support for OpenGL is deprecated and it seems like it works a little less well in every MacOS update. The solution to this is to make sure you have the latest versions installed and to go into the SETTINGS page and turn OPENGL off, then close and reopen the UI. That should make it much better, and if it does, you might want to consider saving these settings over the default preset so all new instances will load with these settings. (While doing so you can change the default UI size and meters and anything you want.)
FYI, the latest Generate and Pendulate release changes the default on Mac to be OpenGL off for this reason, and I plan to do the same in an upcoming Elevate Mastering Bundle release.
