Canvas Backdrop with overlay

Targets Windows

Is this expected behavior?
I have a canvas that I defined a backdrop image for … its the application logo
in the PAINT event… I have it slap a “DEMO” stamp over the logo if it is an evaluation copy of the program

in MacOS THIS works

// Paint Event Code for Canvas - Backdrop is app_logo.png
		Dim x As Integer
		Dim y As Integer
		If PGM_IS_REGISTERED=False Then 
				x=(g.Width-demo.width)/2
				y=(g.height-demo.height)/2
				g.DrawPicture demo,x,y
		End If

but in Windows the STAMP “demo” does NOT appear

to make it work in BOTH macOS and Windows I had to do this

// Paint Event Code for Canvas - Backdrop REMOVED
		Dim x As Integer
		Dim y As Integer
               g.DrawPicture app_logo,0,0,g.Width,g.Height, 0,0,app_logo.width,app_logo.height
		If PGM_IS_REGISTERED=False Then 
				x=(g.Width-demo.width)/2
				y=(g.height-demo.height)/2
				g.DrawPicture demo,x,y
		End If

I’ve always either used a backdrop without paint event or a paint event. I don’t think it’s a good idea to use both.

It’s probably a windows bug where the background is painted after the paint event is handled when it should be done before. It’s worth reporting.
