Pressing F10 will require scaling of all menu sprites to the new
resolution. It used to take like 5s without caching. Now it roughly
takes 1-2s. But you have spotted a bug too! I tested the program and
indeed it is instantaneous when switching in-game. The reason is that
it doesn't scale the menu items. As a result, if you then quit the
game and return to the menu, all sprites will still be as big as in
fullscreen mode, resulted in a clipped screen. I suspect this bug was
present in the older versions too, i.e. before SVG caching was
introduced. I will look into it.
