--- Comment #15 from blc <blc+wine at mail.vanade.com> ---
I see this issue on my Radeon HD 5770, this showed up immediately after the
Shadowlands initial patch and still persists today.  I have not been upgrading
Wine unless things stop working so I don't know the history on the Wine side.

Both the DX11 and DX11 legacy renderer shows this for me.

As far as I can tell it seems something to do with "smoke" areas, excuse my
lack of knowledge of 3D rendering.  Things that seem to be intentionally
blurred to obscure true nature of the object/view are the problem areas:

- tufts of grass
- (cloudy?) sky
- water, fountains and water bodies
- balance druid moon form
- shadow priest shadow form
- many "ghostly" mounts
- Smoky light sources (lanterns, fires) tend to have a rectangular block around
it and also has psychedelic colors around it.
- Death Knight's death and decay spell tends to white out the whole ground also
with rectangular blocks.

Also it appears the longer I stay in the game, some of these issue seem to go
away on its own, or at least they seem to abate slightly or at least seem more
normal.  Not sure exactly what triggers it but it takes quite a bit of time
doing (or not doing) something before things sort of rectify itself.  However,
quitting the game and running it again right away (without restarting the
machine or X) instantly goes back to improper behavior.

The workaround listed above does have an effect but does not completely solve
the issue.

Seeing this in Wine-staging-5.19.
