Transform effect leaves a trail when using the image layer.

[keithudev]

When I want to use the transform effect, to make it move from one side to the other, it leaves a trail. The previous frame should be cleared when moving.

const cursorLayer = new etro.layer.Image({
	source: cursorImage,
	startTime: 0,
	duration: video.duration,
	destHeight: 32,
	destWidth: 22,
	x: (canvas.width - canvas.width / 1.1) / 2,
	y: (canvas.height - canvas.height / 1.1) / 2,
	width: canvas.width / 1.1,
	height: canvas.height / 1.1,
});

const cursorEffect = new etro.effect.Transform({
	matrix: new etro.KeyFrame(...cursorKeyframes),
})

cursorLayer.effects.push(cursorEffect);
movie.layers.push(cursorLayer);
