I have been running Pharo 7.0[.1] for months on macOS 10.14.3 64-bit downloaded with ZeroConf and I have had no stability issues. I leave one or more images open going in and out of sleep on my MacBook Pro. I don't run full-screen, just semi-full-screen (Option-Click the green grow bullet, which leaves the menu bar visible).
But YMMV, it all depends on what you are exactly doing. One (external) library, one different behaviour, one UI change can make a difference.

I’ve also seen a lot of weird things like corrupted fonts and keyboard focus/cursor keys not working properly.

I did notice that half of these images were the rc1 build 1436 setup (as I hadn’t noticed that the blessed 7.0 stable image has a different version number (previously, the last builds in PL Pharo 7 development - was the stable version - unless work then went forward for a Pharo 7.1. I liked to nab the dev version so that I know the build number to report it. I now see the about Pharo in the image also lists this number). Also some of my images were retrieved via zeroConf in the terminal (again, not sure if this makes a difference - but did that a lot with P6 too).
