Software information

I played the Forza Horizon 4's Lego Speed Champions DLC on my Steam Deck using the stable branch and I noticed the ground textures have a odd graphical bug as seen below

UPDATE: I've noticed some surfaces exhibiting the same behavior in the Great Britain map. It did not happen before, so maybe there's been a regression in VKD3D-Proton?

UPDATE 2: I noticed the same behavior with Proton 8.0-2. To add, this happens on snow surfaces, so maybe that needs to be fixed?

So what's the bug exactly? What is it supposed to look like?

The bug is where certain textures during the game's winter season has graphics issues with tiny white pixels scattering all over the ground texture. Not sure why and I don't know if it's worth creating a log since with Forza Horizon 4, the logs can reach 1GB within a minute.

A log is most likely useless, but can you post screenshots of how it looks like on proton vs how it is supposed to look like? I don't see anything obviously wrong in the screenshot above.

edit: I see it now

I'm guessing they mean the small white pixels that are present in the dirt/grass area. You have to view the full image to kinda notice, tho it does look like some kind of bug yes.

Yes, that is what I am talking about. Sorry for not being more clear on that.

It just seems to be the game as i reproduce the same white dots with the native d3d12 on Windows.
