Thanks for your bug report. This has been discussed a few times before, eg. most recently
here. Unfortunately, DPI scaling support is complicated. The way measurements are made, from fonts to GDI drawing to dialogs, on a dynamic, per-monitor basis, requires changes to a huge amount of code. It is on my to-do list and I am slowly working through features that need to be changed. The setting you mention does not, sadly, resolve these issues and, as discussed in the thread linked to above, currently leads to other issues, so I'm afraid it cannot be used for now. If it works for you to resolve the specific issue that you are seeing, that's good to hear though.
