Problems with AIR windows in multi-monitor setup with different font scaling

[DHL83]

I'm developing a multi-monitor Flex/AIR application that uses several AIR windows placed on different displays/monitors that might have different font scaling. I'm experiencing some graphical issues with the Flex components when moving a window from one display to another.

For example, say I have two AIR windows (A and B) and two displays (1 and 2). Display 1 has scaling set to 150% and Display 2 has it set to 100%. At app start both windows will be placed on Display 1. If I manually or programmatically move Window B from Display 1 (scaling: 150%) to Display 2 (scaling: 100%), the components of Window A (still placed on Display1) will suddenly shrink. Window B and its components (now on Display2) are successfully adjusted to the font scaling of its new placement (Display 2).

So the problem is that Window A also gets its contents re-rendered in another scaling when Window B is moved moved to a display with another scaling factor. The problem occurs when <initialWindow> in application descriptor has : <requestedDisplayResolution>high</requestedDisplayResolution>

Is there a way to have AIR applications be Per-monitor DPI Aware ?

I reproduced the same issue using the Starling and Feathers SDK with AIR 29. Is there a solution to this?

I'm having the same issue (described it here Re: How to consider "contentsScaleFactor" for each Window of a Multi-Window App?  before seeing there is already a report in another section)
