Having had problems using other methods, I've decided to stick with CADisplayLink to run my game loop. The animation is smooth now, but sometimes there's a problem where the buttons and other UI elements can't be used, can't be accessed by touch or changed programmatically. This includes UIButtons and UILabels. Has anyone encountered this before?

Is it not a good idea in general to use interface builder and uicontrols on top of an OpenGL view? I've heard they don't play well together but haven't heard the reasons.

Thanks!
