Welcome to the forum!
Interesting.... This is not something I've seen or heard of before. I can hardly come up with any questions.
I would ask if you consider this a high def screen. But by the looks of your screenshot, it doesn't appear to be. It looks almost exactly like my 14 inch laptop screen (except I'm on Windows). Although at the full size, it really is much bigger than my screen. I'm not sure if you zoomed it, to make the problem easier to see, or if that really is the size of your screen (which is huge, to me - easily twice the size of mine
)
We have seen some issues somewht like this in high def or high res screens. As far as I recall, it's expected to be fixed.....hhm, can't remember if it's the next upcoming point release (0.92.2), or the next major version release (0.93).
However, from what I recall, those problems affect all parts of the interface. But the affected parts in your screenshot are only particular parts of the interface.
On Windows, I know that the text in all the areas in your screenshot are all part of my system theme. So if you know the Mac system well enough look into however display themes are handled, that's one clue that you can track down. Maybe a different theme would fix it?
Meanwhile, I'll do a little research into existing bug reports. Maybe something will turn up there.
