JunitTest_toolkit_complex failing on Win 10 with HiDPI

I'm setting the Subsequent test toolkit fail on my Win 10 machine require HiDPI. Any idea if this 
is a problem with the test or if it's showing a problem with LO's HiDPI support?

Steps to reproduce:
1. In win 10, Settings -> Display -> Scale -> 125% (or more)
2. Reboot
3. $ make JunitTest_toolkit_complex


The test passes at 100%, but for 125%+
