Hello,
I'v noticed that david is changing frequency of the projector, is that true? technically no, but I did some investigations:
I used patterns amde in flash and used them in full screen on my projector with camera on projection. No flickering effect at all...
When I turned on David and projector shows patterns, insane flickering effect appears.
What is the difference of david patterns and any others? What could it be?

No, DAVID does not change any projector settings. The pattern projection window is like any other window.
Which projector do you have?
When you set DAVID to project the patterns on your monitor (screen ID) what happens?

Hello Sven,
My projector Benq MP525, camera: point grey FMVU-03MTM.
As only I set Structured light setup, projector goes into blue screen mode (it does that every time resolution is changing) and in 1-2 sec projects normally.
I also checked patterns I made for test in flash and no resolution changes appears that's why I suggest david could be changing something, resolution or frequency.
This effect not very noticeable with Logitech c525 and can be compensated with drivers features. With ptgrey I cannot compensate flickering with FPS or exposure (as only David is closed, everything goes back normally)
Any suggestions what could cause this?
