sdl2 renderer: remove the random flashing black borders

Browse Source 
on the batocera linux distribution (https://github.com/nadenislamarre/batocera.linux),
retroarch gives some flashing black borders sometimes when running a game.
It looks like sometimes the rendering is done without clearing the screen causing
this flashing effect.
