ubuntu-MATE - top of windows disappear under panel

UBUNTU-MATE or MATE (1.20.1)

rflbianco's comment may 10, 2018 (I opted not to comment there)

I have two monitors, one above & slightly to right of the primary one (primary is bottom, and to left of one above it; overlap is about 66%). When I typed `ubuntu-bug` into mate-terminal and apport window opened, the top of it including minimize/maximize/close buttons were hidden by top panel (primary or my lower monitor).

My theme is Panetheon (with dock on left on bottom/primary monitor with 'show hide buttons' naturally ticked to enable me to access hidden top of windows.

Most new windows are opened top left on my primary (lower) monitor (eg. just now I opened "about me" & its top left without minimize/close or "Mugshot title bar visible UNTIL i click 'hide panel'. To view the button top left of window requires me to click 'hide' on the right side of monitor which requires mouse movement.

This does NOT cause crashes or anything. Its just annoying and I'm opting to use XFCE (which is also installed on my box). It's been doing this since I dist-upgraded to 18.04 (from 17.10). I can re-produce easily as top left appears to be default position for windows to open (with exceptions; eg. chromium doesn't open top left under panel, but in its last position).

I bumped my box to 18.10 (development), and issue still occurs.
