pixel based layouts not working

Positioning layer or text based on pixels shows completely different kind of layout in runtime 2 than in runtime 1.

Added example which has two layers with pixel based positioning with one relative to top and one relative to bottom (which gets y-flipped in runtime 2).

Also note that the text element placed in percentage based layer is not in same position with runtime 2.

Runtime 1 viewer has the correct resolution of the presentation while runtime 2 scales it. I guess highdpi plays a role but the issue can be reproduced with 100% scaling and 1920x1080 resolution as well.
