Screen Shots Showing Scaling Differences

Can be overcome, so not critical, just annoying.  ;)

OSX 10.15 (Catalina - Cannot say for sure if other versions of MacOS are affected.(

I believe this began with LO v7.0

When using identical multiple monitors with different scaling, neither Calc nor the macro IDE render properly on the monitor scaled to less than 100%.

Using two identical 28" 4K monitors (3840 x 2160).  One is scaled to the default (100%), while the other is scaled to appear as 2560 x 1440.

Please see attached screen shots.

Dragging a calc window back and forth between the screens reproduces the look.

Dragging a macro IDE window to the other screen does NOT reproduce the look.  It depends on where it was opened.  If opened on the "100%" screen, it looks OK, and remains OK even after being dragged to the other screen.  If opened on the "scaled" screen, it remains wrong even after being dragged to the "100%" screen.  

When "wrong", the IDE inconsistency can be reproduced by using the mouse to click into the library drop-down.  If keyboard arrows are used to navigate to a library, the drop-down changes to look OK until the mouse is again used.  The code area always appears to look OK.
