if you use the drawImage method with a video as a source and change the source dimensions (skewed or scaled proportionally) safari crashes after a couple of seconds, current workaround is to change the dimension of the canvas and reposition/crop the canvas itself

void ctx.drawImage(image, sx, sy, sWidth, sHeight, dx, dy, dWidth, dHeight);
