If the DOS game you are running relies on certain VGA raster tricks that affect active display area, enable this option.

This adds a delay between VGA mode changes and window updates. It also means that if you are capturing a demo or game, that your capture will also show a few garbled frames at any point mode changes occur, which is why this option is disabled by default. If you intend to run certain DOS games and demos like DoWhackaDo, enable this option.
