2021-02-17Fix: [SDL2] simplify what to redraw to prevent tearing (#8685)Patric Stout
When there are a lot of rects to redraw, of which one of the last ones is almost the full screen, visual tearing happens over the vertical axis. This is most visible when scrolling the map. This can be prevented by using less rects. To simplify the situation, and as solutions like OpenGL need this anyway, keep a single rect that shows the biggest size that updates everything correctly. Although this means it needs a bit more time redrawing where it is strictly seen not needed, it also means less commands have to be executed in the backend. In the end, this is a trade-off, and from experiments it seems the approach of this commit gives a better result.
