When I'm building wine with new experimental wow64 mode, it is unable to
properly show or render application windows for some applications.

I've tried it both on clean prefix and on existing prefix.

I've tried Steam setup and Battle.net setup, both failed. With Battle.net setup
I see no window, with Steam setup I see black window with some artifacts.

When using multilib wine built old way, everything works as usual.

Happens both with wine 8.0 and 8.1.

OS: Gentoo Linux amd64 (64bit)
Graphics: X11
