Hello Martin,

sorry for being a bit late with this. I have tested and it was very
strange, so I realized I need more time to play with it.

Here is how I got it:

If I pass parent in the frame-params list to make-frame, then all is
grandy-dandy; but if I don't then the behaviour is as following:

If parent is set after creation; the frame will be reparented correctly
and appear at correct place on the screen, but it won't switch focus.

If parent is not set after the creation; the frame will switch focus,
buf it will of course appear somewhere at the screen (absolute
coordinates I guess).

I have tested only emacsclient. I hope it helps.

I have attached a simplified test file:
