This is a very old one, but as far as I can tell, not reported until now (aside
from some side-mentions).

PlayOnline Viewer, which is used to launch Final Fantasy XI Online, has a
blank/grey window for its "splash screen".

It has been working in Wine Staging for some time.

Not sure if related, but comparing the logging between runs, each of these show
up twice with Vanilla but only once with Staging:
