The lines don't really change, "M-x redraw-display RET" returns the display to the expected state.* It happens for me on Debian 9.11 and 10 (in a clean VM), should I try another OS? * Just pressing "M-x" changes the display. With the first variation (i.e. ... C-e RET DEL M-x) it returns the display to the expected state. With the second variation (i.e. ... C-e a RET M-x) it correctly displays "line 2" on the second line, but doesn't clear the third line; when I continue with "redraw-display RET" the third line is cleared, returning the display to the expected state.
