Rendering Artifact on iOS 18: Corners Appear on Circular Touch Visualizers

[landabaso]

First of all, thank you, @KaneCheshire, for sharing ShowTime. It's very useful for recording videos visualizing touch interactions.

On iOS 18, the touch visualizers (intended to be circular) sometimes show rendering artifacts, with corners appearing on the bottom-right side of the circle. This issue does not occur on iOS 17 (did not test earlier versions), where the touch visualizers render correctly as circles.

Hi @landabaso -- I didn't "fix" it but manually changed ShowTime to inherit from UIView instead of UILabel and the rendering artifact disappeared.

If I had to guess, something changed in iOS 18 that messed up with how UILabel is rendered.

If you don't care about showing the tap count maybe this will help you!
