Flaw in displaying an image over a viewFactory:catalog_photo on Windows

[rderimay]

On Mac everything is working fine, but on Windows, when I display an image over a catalog_photo in a dialog, it is displayed with a grey background instead of a transparent background (even if I set background_color to LrColor()

Has someone encountered this sort of problem or has someone an idea where it could come from ?

Thansk !

I think the underlying cause may be the same as for this issue: Re: Responding to clicks on viewFactory:picture()? Windows and Mac obviously don't behave the same with respect to overlapping controls :-<

Don't think so... A simple test like this

viewFactory:view {       
viewFactory:picture {         
value = _PLUGIN:resourceId("assets/imgs/_focus_point_red-fat_center.png"),         
background_color = LrColor()       
},        
viewFactory:picture {         
width = 600,          
height = 400,           
value = _PLUGIN:resourceId("assets/IMG_8576.jpg")       
},        
place = 'overlapping',      
}

will bring this :

this looks like the small icon's background is not transparent over the underlying image but over the dialog, which is wrong.
