Note that we introduced several improvements regarding DPI scaling in 2018 R1 (version 2018.1.116).
After further investigation we have found out that one of the problematic DPI scenarios handled in 2018 R1 was ERP Demo scaling. The issue was handled by improving the RadFormControlBase class. It seems that this change have also fixed other RadForm cases. Please accept my sincere apologizes for the inconvenience caused by not updating the public item earlier.
Feel free to test your scenario with Telerik UI for WinForms 2018 R1 (version 2018.1.116) or a newer version.

I believe this issue is fixed in 2019 R2 and not in 2018 R1.
