FGU Looks small on Mac Big Sur

OK, this one is bizarre, but Fantasy Grounds seems to have adjusted its size and now appears super tiny. It used to be that when I set my Mac to the same screen resolution as my PC (2560 x 1440), they were of comparable size. Not anymore. I have both set to a UI scale of 125, but the Mac version is taking up about a quarter of the space of the PC version.

I have attached screenshots to show the difference. The PC was taken on a 2560 x 1440 resolution monitor. The Mac version was taken on a 4K monitor, scaled to 2560 x 1440. Oddly enough, when I change the scaling on the Mac, the image leaps in size when I change it to the 4K resolution (which should be the smallest). I actually have to set the UI scale to 250 to get the same visual quality

This is due to the Retina display. Use the chat "/scaleui xxx" command. Somewhere in the 200-400 range should give you a happy size.

OK, I replaced a Mac Mini with a Macbook Pro capable of driving two monitors, and a new sizing weirdness has emerged.
I have two monitors. One is an LG 4K (3840 x 2160) and the second is an HP WQHD (2560 x 1440). I have scaled the LG down to match the HP, and almost -everything- maintains the same size when I drag it from one screen to the other.
Except Fantasy Grounds. If I start on the HP and drag it over to the LG, it actually shrinks the image even though they are scaled to the exact same size.

I've attached a screenshot to show the difference, and included the same picture on both screens to show they are scaled the same. I've tried fooling with the scaling but FGU acts weird, getting smaller on the 4k until I reach the 4k setting and the snapping to a larger size.

Not entirely sure about Macs, but there are two things to keep in mind about FG: 1) Mac Retina displays usually will require UI adjustment on FG. 2) FGU is running in Unity. If you ran a game written in Unity in a window and moved it between the two monitors, will it stay at the same scaling?
