Symptoms

Silent Hill f will crash during certain parts of certain cutscenes under specific conditions with 100% reproducibility. I will post a video of how to exactly reproduce the crash and attach save games below.

The conditions needed for the crash to occur that I have figured out thus far are:

• the game's speech and text language need to be in Japanese
• the needs to be in fullscreen or borderless, not windowed mode

This is a regression in Proton Experimental Bleeding Edge. I have bisected this (by downloading specific tags of Bleeding Edge with the steam console) to have started with experimental-bleeding-edge-10.0-265592-20251103-p65da75-w8b0c29-de9ad90-vda1f4f. So it should be wine commit 8b0c29f5b that causes the issue. This regression in definitely unrelated to vkd3d-proton, using latest vkd3d-proton git dlls dropped into "good" Bleeding Edge versions do not cause the issue.

Attaching gdb to the game, I get this output after a crash:
