First time submitting -- apologies if I'm missing anything obvious.

Firstly, the regression was tested using the git repos from wine's 'wine-5.0'
tag and wine-staging's 'v5.0' tag.  The issue is still present even with the
wine 5.3 versions, but when I tried to follow the regression tests, I was
failing to compile.  I might've screwed something up, I can try again if you
need me to, but I am a bit of a derp and I'm punching upward.  The output I got
from the regression test (following instructions from
https://wiki.winehq.org/Wine-Staging#Reporting_and_debugging_bugs_against_Staging
) was:

Second, the game currently requires ntdll-Hide_Wine_Exports, and it works fine
with just that, and people can use an older version of Proton / Wine and that
works around the problem too.

Finally, the actual problem:
If ReShade (or GShade, a fork of ReShade) is installed with FFXIV, as soon as
you get into the game itself (not the launcher), the game works perfectly fine
unless you move the mouse.  As soon as you move the mouse the game freezes from
around five to ten seconds every time you move the mouse, making it effectively
unplayable.  This did not happen with Wine-Staging prior to 5.0.

Reproduction:
1)  Download and install FFXIV (I realize Lutris is an extraneous program and I
can go through the details, but I'd just be repeating what the scripts at
https://lutris.net/games/final-fantasy-xiv-a-realm-reborn/ say to do / what's
required.  I can add the info if it's preferable).
2)  Download and install a shader program (I use GShade, so instructions are
based on that arbitrarily, but I confirmed the same issue with ReShade):
2a) Easiest installation is to download
https://github.com/Mortalitas/GShade-Shaders/releases/latest/download/GShade.Latest.zip
into the prefix/drive_c/Program Files (x86)/SquareEnix/FINAL FANTASY XIV - A
Realm Reborn/game/ directory and unzip it.  Also download
https://lutris.net/files/tools/dll/d3dcompiler_47.dll to the same location.
2b) Add overrides for d3d11 (native,builtin) and d3dcompiler_47 (native) to the
prefix.
3)  Run the game, sign in through the launcher.
4)  When the game loads, move the mouse.

There's no output of the issue such that I can see by default in the console.
