When I open a standard size rc10 terminal from winbox 2.2.11, and then I maximise it (using 1280*1024 screen resolution) prompt line gets faulty and has strange behaviour. Prompt doesn't update its position, as you can see in the attached image.
When I close this terminal, and open a new one, terminal size is stored, so the new terminal has this size, and it works correctly at this huge terminal size. It can be resized and maximised without problems.
