Can confirm this behavior (tinySA_v1.3-347-g31eb02e):
I see this white line when clicking BACK in one of the following menus:
- LEVEL
- TRACE
- MEASURE
- CONFIG
To me it looks like the problem only exists when a menu (its menu items) takes up all the vertical space.
(I also noticed that pixel height of the menu items is slightly different in the various menus)
When clicking MODE > Return to LOW, the white line disappears again.
