I think this is a long standing issue with SDL, and hence effects Mojo, I’m not sure if the same happens with windows, but it wouldn’t be the first time I’ve come across a platform bug!
Anyhoo… I have noticed that if you keep dragging a window to continuously resize it, when you stop resizing the window keeps following the path you made while dragging the resize around. If you keep going in circles for a minute it might take a minute or so to catch up.
I’ve seen this issue years ago when directly accessing xorg from python (via clib) but I can’t remember the work around and its not a codebase I have access too any more… terrible memory…
