Actually, it should not be "just like B&R" (that has its UI completely messed up on high DPI), because unlike B&R this product was written on the modern UI framework that does support high DPI out of the box.
Sure, just like in every other part of the product, there could be bugs in UI too - minor issues on certain specific scale levels our QC did not test, and no beta users have spotted... after all, it is v1. Just throw them our way via screenshots, and we will address!
No worries, QC folks were able to emulate 4K monitor in VMware Workstation and saw the new DPI options appear in Windows (200% and 250%). And as soon as we enabled those, we saw the issues. Funny thing, but it all comes down to a problem with only 2 UI controls at these DPI settings, however one of those controls is used pretty much everywhere... you've probably guessed it already, title text. Thus your long list
