I'm afraid so.

For what it's worth, note that setdisplaymode() is only called by
testdisplaymodes(), which is guarded by "if (winetest_interactive)".
Practically speaking, that means I've run that test twice in the past
10 years, one of which was today. It fails with "ddrawmodes.c:576:
Test succeeded inside todo block: Fullscreen window has wrong size",
so I doubt a lot of other people are running this regularly either.
