On all my browsers here it animates smoothly enough (good frame rate), but every time it renders changing parts of a frame there’s some flashing effect, and as a result when the car is moving fast looking at the background is pretty unpleasant, especially skinny high-contrast elements like the trees and posts against a white background Maybe that’s just inevitable when using the canvas for painting?
