Bug ID: 51323
           Summary: FFXIV: XIVLauncher fails to inject plugins as of
                    wine-5.19.
           Product: Wine
           Version: 5.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32

XIVLauncher (a third party launcher [that can be found at
https://github.com/goatcorp/FFXIVQuickLauncher/ ] for Final Fantasy XIV) allows
for the injection of plugins into the game.  There's even a Lutris installer
script that automatically sets it up ('XIVLauncher version', from
https://lutris.net/games/final-fantasy-xiv-online/ ), and it works just fine
unless you try to update to a more recent WINE version.

I ran a bisect, and found it to be commit
0c631ebb2354334eaf309bc0765d3283654cf902 preventing the plugin injection.  If I
revert that commit from the 5.19 tag in git (and compile in staging's Hide Wine
Exports for XIV), the plugin system works in-game without issue.

I don't see anything that looks relevant from any log -- not even from
XIVLauncher's.

I'm far too caveman to be able to do anything further on my own, but that's
what I've been able to figure out so far.  If there's anything else I can do to
further the issue, please let me know.

As always, thank you guys for all your hard work!
