mlterm does not redraw terminal after switched PTY via NEXT_PTY with hotkey. I got PTY looks like blank. If I press any key, foreground application like editor or shell redraws PTY.
This bug occurs when I set non-antiareas font and big "geometry" parameter on .mlterm/main.
Exact geometry parameter which yields this bug depends on using font (and maybe screen resolution too). For example, this redraw bug occurs when I set geometry=110x79 for M+ font. But geometry=110x78 is ok.
Additionally, when I set geometry=110x79 or above, suddenly mlterm maximize its height.
When I change terminal size interactively with mouse, this bug does not appears.
