This error occurs when a components gets drawn at a really small size and its constraints compute out to be invalid. For example, if you have: Once the component containing this rect is only 3 pixels wide, the width will be computed as –1 since the left side will be at 2 and right side at 1 and (right – left) = -1.

yes, but you trigger it, because the drawing and other visual functions are not called instantly, but on every timer tick, and the timer's speed is 24 ticks/sec by default. so at every tick spark askes every component if the visuals have changed, and if so, calls the redraw, and thats where it goes back to your code..

it depends on your code. error finding method: comment half of the block.
