Description Ivan 2021-01-29 10:04:27 UTC 
Under Windows:
 1. Create a window without SDL_WINDOW_RESIZABLE flag 
 2. Call SDL_SetWindowResizable() to make it resizable.
 3. Try to resize it and get a SDL_WINDOWEVENT_SIZE_CHANGED with WRONG window size (width and height is decreased by 10).

This happens if no SDL_SetWindowSize() is called between 2 and 3. 
Because Windows needs to update window size via MoveWindow() when window's style (border type) is changed, otherwise it reports wrong client area.
Comment 1 Ivan 2021-01-29 10:06:46 UTC 
I'd suggest to add MoveWindow() call after SetWindowLong() in WIN_SetWindowResizable() in SDL_windowswindow.c
