Scaling issues on macOS when moving window between different screens

[BenBergman]

When I move a window between monitors with different levels of scaling, the contents of the window grow/shrink proportionately.

This might be related to #350, but since I'm seeing it on macOS instead of Linux it seemed a new ticket was appropriate.

@BenBergman thanks for opening the issue! I have a feeling that #350 indeed be related - this leads me to suspect that this might be something to do with vulkano-win, or perhaps the way we're using it.

Out of curiosity, does the behaviour correct itself if you manually resize the window after moving the window onto the screen with the different DPI? If it does, it might just be that we should be re-creating the vulkan swapchain when receiving the HiDpiChanged event (at least I think it's called something like that).

Unfortunately, resizing does not correct the behaviour.
