Crash resizing demo's window #1 #94

Closed nitrix closed 2 years ago

nitrix commented 6 years ago

Hello.

I was playing with the demo v0.5, went to gui > window and tried resizing the "Window 1" when I got a crash. This is reproducible every time for me on Windows 10.

panic: runtime error: invalid memory address or nil pointer dereference
