PR from space-wizards#6758 northwesternbear on discord

Steam does not behave well when multiple double buffered windows exist from one parent process, this PR fixes the memory leak by disabling double buffering on all secondary windows.

Known Issues:

  • If you shift+tab to open the overlay while having a pop-up focused the overlay will draw to the main window (at the wrong size) but leave the inputs (close interaction, buttons, etc) on the pop-up
