Original Pull Request: https://github.com/microsoft/terminal/pull/1134

State: closed
Merged: Yes


Summary of the Pull Request

Currently, the program crashes with a window width or height greater than 32767 (accounting for window decorations). This can be caused when the initialRows and initialColumns settings are set too high (also depends on the font width and height). This fixes the issue by not allowing the window to expand beyond 32767x32767.
