The 19.05 UI is a mess of mismatched icons sizes and also behaviour on my hi-res laptop screen and my normal-res second screen. Here's a sample when viewed on the second screen:
See the highlighted icons - they are probably scaled correctly on the second screen, but nothing else is - it's all gigantic.
On the hi-res laptop screen, these icons are literally miniscule, but other things are normal size.
On neither screen is the UI working properly. This is going from 18.07, which was working correctly on exactly the same OS, physical computer set up etc.
