KLCK: Shape bitmap texture not working outside of editor

Shape bitmap texture works as intended within the editor and even works in runtime when the source is either the gv pointing to a wallpaper or the album art from a music player, but fails to work in runtime when it is a YouTube thumbnail that has been stretched to fill the entire screen. If I don't resize the shape to be so big that a 16:9 image fills the 9:16 screen, it works as intended but then I have letterboxing going on. When I make it big enough to eliminate the letterboxing it only works in the editor for reasons unknown.

Attached are screenshots to show the problem and a debug log as produced by the editor.

Also note I am running the update released today, Jan 3 2019.
