Your apitrace ends immediately after loading. The character doesn't even move a single meter or leave the house.
The one second I saw in-game rendered correctly on my RTX 3090.
The instructions for tracing said to close the game as soon as it starts happening. In fact, even the menus are a bit glitchy.
I'm not getting any validation errors. This is most likely an Intel driver bug. You should report it over on the Mesa repo.
I am not reproducing anything like this on ANV + Lunar Lake, so it's most likely an ANV bug specific to older Intel hardware.

Additional Information
It does NOT appear to happen on the released 2.7.1. I don't know exactly when it started, but it seems that it's been happening since at least September 21, 2025, since that's when Proton GE-16 released, which is the oldest version that ships with a post-2.7.1 DXVK.
