It looks like that GetKeyState is supposed to catch key presses when called from a background thread even after its thread message queue and thread input structures have been created.
This happens in Bioshock 2 Remaster, and causes the game to stay forever on a "Press space to continue" screen, as the thread checking for space key press calls GetKeyState repeatedly (and PeekMessage), although it's in background.

Hi,
While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

Please, just ignore this, I'll send an updated version.
I think the two cases where GetKeyState is reportedly failing, are actually because the created window steals foreground from the main thread even if the main thread calls SetForegroundWindow/SetFocus right after.
Adding SetForegroundWindow/SetFocus call in the "background" thread to restore focus to the main thread as it's supposed to be, makes GetKeyState calls from this background thread catch the key presses even if that thread doesn't peek its messages.
My understanding is then that GetKeyState returns some global (process-wide?) state, that gets updated by whichever thread is foreground as long as this thread peeks its messages, and regardless of what the other threads are doing.
I'm also not entirely sure that keybd_event behaves exactly as if a user is pressing the keys, but there's some obvious issues with Wine implementation nonetheless.
