On screen terminal breaks when too small #2611
Description
I don't have the precise cause yet, but if you do stuff that tries to print too big to fit in the terminal (maybe too wide in one string?) the terminal's IMGUI code throws exceptions and you see the terminal blinking green on and off (the keyboard focus keeps toggling on and off). This is more than just a cosmetic annoyance, since when this happens the terminal stops working entirely and you can't type any new commands until you reload the scene.
When that happens this message spams the log:
ArgumentOutOfRangeException: Argument is out of range.
