This is not really a bug report but rather a question or ask for thoughts from DXVK team since the problem is happening with and without DXVK with different versions of Wine (staging, ge-proton).

I'm playing the first release of Half-Life 2 (build 2153) on my Steam Deck OLED.
While playing the game I found a very weird effect in one of the scenes at the beginning of the game when Alyx is teleported from a lab after meeting Gordon ("A Red Letter Day" -map: d1_trainstation_05-).
While standing away from some objects and NPCs they look like "greyed out":

but as I get closer to them they look as expected:

I didn't progress much in the game yet, but so far I was only able to notice this issue in this specific part of the game (not sure if it will happen later as well) and I'm wondering what can cause it (an issue with Wine, a bug in the game -bearing in mind that it was the first release, etc.) and if maybe there is some dxvk config parameter that can help mitigate it.

My dxvk.conf file looks like this (otherwise the game will crash: #2330):

[hl2.exe]
d3d9.maxAvailableMemory = 2048
d3d9.memoryTrackTest = True

As a side note, without DXVK (wined3d) and specifically using Wine-GE-Proton8-26 the game looks much more darker (I don't think it looks as expected) but also the issue doesn't seem to happen (or it is just so dark that I couldn't notice it):

With Wine staging 10.7 the game looks the same with and without DXVK.

I can provide Wine and DXVK logs or an apitrace if needed but since the issue is happening also without dxvk I don't want to take much of your time.

Thanks!
