This is a bug that I've seen reports of going back at least 7 years and have
been encountering myself. But I appear to be the first to have actually traced
it down to wined3d. It happens on wine, wine-staging, all currently available
versions of proton and generally just everywhere.

Overview: 
The game has a choice of several 3D rendering APIs (Primarily: DX6, DX7, GL,
Glide), but it also has a 2D rendering layer that is used to render it's GUI
which always runs on ddraw no matter how the game is configured. This means
that in both wine and proton, and even if using d7vk which delegates 2d tasks
to wined3d, this rendering is always wined3d's responsibility; hence where the
bug must be.

As for the bug itself, there are several 'dynamic' fields in the GUI where the
background behind those fields have a permanent ghosting effect, anything
rendered over those fields will leave behind a trail behind. More often than
not this ghosting effect will be displaying cursor trails.

I've attached a visual example as well to showcase the issue.

You can also see more examples on the game's proton git page as well:
https://github.com/ValveSoftware/Proton/issues/1805

Another potential hint about the nature of the issue is that most of the
affected surfaces should be a solid black color, the kind that's not a texture.

The only workaround I've been able to find is to use
dxwrapper(https://github.com/elishacloud/dxwrapper) but it's likely other
wrappers like dgvoodoo might work, I just haven't been able to launch the game
with any of them.

Steps to Reproduce:
 - Launch the game, doesn't matter how it is configured so long as it runs
(default should work)
 - Either load a game or start a new game
 - While playing, hover the mouse over the HP display (numbers on the
right/left edges of the screen)

Actual Results:

The cursor left a trail in the background behind the HP numbers.

Expected Results:

Background behind the HP number should remain black, always.

The console output didn't seem to contain any useful info, this about sums it
up.
