When I run cargo run --example transparent instead of a transparent window I just get a white window with no decorations.

It seems the problem was introduced in this PR:
#2419
If I revert to a commit before that PR was merged, then I see no GUI window showing up at all which I believe is the intended result (I see the icon in the taskbar and it appears in the alt+tab window list).

When I run the transparent example on the latest commit I just get a white window (with the expected icon in the taskbar)

I am running Windows 10.
