Key Editor bug in Cubase 10?

Sorry to be a pain in the a… but I find it hard to believe that I’m the only one with a 4k monitor running full res. on Mac???
Will you take a look at this and tell me if you have the same problem?

Same behavior on Windows 10 here with my 4K monitor. Definitely needs to be fixed.
