Yeah, I'm aware of the flickers in some examples. Apart from the fact that if you draw stuff too fast it might cause flickers, I'm also doing everything on a single thread and the examples were written more as a way for me to keep track o breaking changes and to show people how the library works and more or less, so I didn't want to make the examples more complicated than they needed to be.

But I will take a look and fix them over time I'm sure.
