I was affraid of that... Windows, as I observed yesterday by accident, does some kind of window redraw, when I drag it between two screend with diferent DPIs. At certain point it - as I suppose - sends to a window a redraw request and provides it with a diffrent DPI setting, and you can easily bserve the window being redrawn with a ew DPI. I hoped we could obtain someting similar...

In theory™ such could be achieved on the client level, ie. if you move a 
window, it checks where it resides, calculates the natural dpi from device 
measures and resolution, alters (in case of Qt, not idea about gtk ;-) the 
device pixel ratio setting and cause a full update.
Of course you're still in some conflict whenever the window is between two 
screens.
