I am on a retina display Mac. I have done the suggested fix of setting my resolution lower. This has no affect on the Steam overlay in TTS. It is extremely tiny, which in itself would not be an issue, but I can’t click on any of the buttons at all. The mouse pointer stays behind the overlay on the table. That means I can’t invite friends into my games.
Mac OS 10.14.6
Using Metal will fix this issue.
As far as I know Metal is used by my iMac by default.

When you launch the game choose Metal as the option.
I don’t see where I can choose metal as an option.
I figured it out. Steam overlay seems to be working this way.
