For the records:

This PR as a solution for this issue #17439 solves the problem of @riuttner on Mac but introduces a new issue on Windows, specifically Windows 11 with two monitors where Pharo freezes when the image is moved to a second screen.

This new issue now on Windows is described also with a video in #17512 (comment)

Best will be another new PR setting "SDL_RENDERER_PRESENTVSYNC" for Mac and 0 for Windows/Linux (as before) within SDL_Window >> createDefaultRenderer

As far as I know, we do not want SDL_RENDERER_PRESENTVSYNC flag because it deprives the VM of execution time. We'd waste CPU time that VM could use. With VSYNC enabled, SDL_RenderPresent doesn't return immediately; it does a wait to synchronize with the refresh rate. SDL_RenderPresent is FFI-called by OSWindow-SDL2 each time a new frame is ready to be shown on screen, e.g. on every mouse move or text cursor blinking. @tesonep

I guess the problem on Windows then could be due to SDL_RenderPresent waiting forever when the window is moved to the other screen. That should maybe be checked and, if needed, reported as an issue with SDL. The test code in SDL issue #11384 might be useful (again, I used it for SDL issue #11569).
