How to stop WiXUI flickering

I've been playing around WiX lately, and I have found that WiXUI wizard is not flicker-free. When you click "Next" to advance to the next step in the wizard, the wizard window is actually destroyed and then a new window is created with the next step. This does not allow for clean transition between "wizard pages". I come from Inno Setup, where this is perfect, no flickering or window recreati开发者_如何学Goon at all.

1. Is it possible to achieve flicker-free wizard steps transition in WiX, and how?

2. Is it possible to create my own wizard GUI (in C++ or Delphi), which would WiX use instead of the WiXUI?

That's how MSI handles the NewDialog control event. If you want complete control over UI, you need an external UI handler, like Burn in WiX v3.6.
