Resizing window too small crashes app #1100
Description
Users are reporting situations where they try to make the application smaller, which leads to the U/I becoming unresponsive even though the window can still be moved around. I've also seen this happen sporadically but never made an issue of it

You can set the minimum size of the window based on the GUI backend? (qt, glfw, or anywidget).
That traceback is weird though, I know the wgpu negative viewport size one though.
