Interesting, you are not double buffering. Now I know why U++ apps feel so responsive and 'light' when resizing. Well, I have to admit that I am surprised that more of your controls, text, etc. do not flicker more than they do. But, basic stuff in that example flickers, so I'm guessing that in most complicated/phat apps, double buffering will be preferred. How do I easily turn on double buffering for the complete app at once? Is it a big performance killer in U++?

Just put BackPaint() in your app constructor. There can be some slowdown but it is only visible if your hardware is old.

Well, to be more correct, call it for all of your main windows...

In fact, I think that we should backpaint much more than we do now, virtually all of "small" Ctrls. Maybe the BackPaint (or better Transparent, which implies BackPaint) could be default...
