The problem with setting it back to 1000 it will require a lot of memory again. We maybe need dynamic resizing. |

The ncurses pad used for rendering window history had a fixed height of 100 lines, which caused "Ncurses Overflow!" errors and broke scrolling once the content exceeded this limit. This commit replaces the fixed limit with a dynamic resizing strategy. We use a minimum height of 100 lines. If a pad reaches its threshold of 3000 lines, a full redraw is triggered to reclaim space from discarded messages and reset the pad height. Pads are shrunk back to the minimum height during every redraw to minimize memory usage for inactive windows. Message history should always be smoothly scrollable now. d7e46d6 set it from 1000 to 10000. f27fa98 set it from 1000 to 100. Probably also relevant is 4fe2c42. Close: #2074 Fixes: #2045
