This project demonstrates how to fix the common bug causing flat or cut-off sides by adding a transparent rectangle. It also demonstrates that the transparent rectangle is not detected by the "touching ..." sensing block, which is very useful. Note that @kriblo discovered that using this technique on a large number of moving clones, especially if the rectangle is very large, can have a slight negative impact on performance when changing costumes. See @kriblo's project below for a demonstration.
