The problem is, that Java  doesn't support fractional scaling (I think it's because it still uses X11)

I use 175% and in theory, FlatLaf can do fractional scaling, but not all parts of NetBeans are scaled properly
when using flatlaf.uiScale=1.75

But FlatLaf also supports fractional scaling smaller than one, so I ended setting making Java scale by 2
using -Dsun.java2d.uiScale=2 then make FlatLaf scale it down using -Dflatlaf.uiScale=0.875

As you want to got to 150% you need -Dflatlaf.uiScale=0.75
