Hi, 
Some RPG Maker games, epsecially the ones from the MZ variant, where sometimes
some key press events aren't handled properly and are replayed in a delayed
manner often more then once. Most games experience this issues in dialogue,
where the dialogue start skipping fast without any user input, but there is a
game Mansion Tour that is having issues even in the map or in battle mode.

The +key log show that when this happen it register a KeyPRess but after  the
NtUserTranslateMessage 1 -> PostMessageW(0x300ba,WM_CHAR,<x>,001c0001) for <x>
in L"\r"
there is not corresponding KeyRelease. This key is the key that after other
inputs start replaying more the once delayed.

This seems linked to the QS_DRIVER bits to be setted in msg_queue_poll_event 
but then removed from set_queue_mask.
I checked that removing the bit clear from set_queue_mask correct the issue too
(even if not correct)

Dupe of bug 58908, though it seems the solution from bug 58893 won't help
neither here nor there.

The user that reported that bug reported that adding that XFlush worked for
him, but it doesn't work here, not surprisingly. Seems another XFLush,
somewhere near input handling should be needed. Not sure if the mix of poll and
epoll can cause some issues.

edit: for some reason I read the 2 bugs as the same, so the first part of the
post before doesn't make much sense.

I've tried that game but it doesn't seem to start, is there anything that needs
to be installed first?

I tried a couple of other itch.io games tagged as RPG Maker MZ but also not
been able to reproduce the issue.

Which desktop environment are you using? X11 or XWayland? Any IME involved
maybe?

Would you mind making a log with
WINEDEBUG=+timestamp,+pid,+x11drv,+event,+win,+key,+msg,+message,+imm,+xim

Hi Rémi,
This is under X11 and KDE Plasma 6.5.1. No IME involved.

I didn't install any prerequisite for it to work (and prefix is new)

Created attachment 79616
  --> http://bugs.winehq.org/attachment.cgi?id=79616
log with requested debug

This is the requested log, with experiencing lost input in main menu and with
fast skipping dialogue (generally triggered by Enter key, enter was one of the 
input skipped in main menu) in the new game scenario
Added a -dxgi to prevent some spam from a semi stub dxgi function
