First of all it would probably be good to try with latest vkd3d-proton and not with some old build from proton-ge 10. Mesa 26.1.7 is also old and is not what is shipped by Arch currently. Also you could just include the full proton log compressed as .zip instead of letting some AI generate questions.
I have updated to Mesa 26.2.1 and GE-Proton 11-6, and retested. Here is the Proton log from the crash. The issue persists.
Full environment info:
Mesa 26.2.1
Linux 7.1.9
linux-firmware-amdgpu 20260810-2
RX 6700 XT
GE-Proton 11-6
vkd3d-proton build c9c6bf2e9c18252 (the crash log reports application version 3.1.0; build information is on lines 8052-8053)
One additional piece of relevant information: I experienced this same crash behavior in Monster Hunter Wilds in 2025. MHWilds also uses RE Engine, and is likely on a similar version of the engine to what Dragon's Dogma 2 has just updated to.
Also, my system is running Omarchy rather than stock Arch, so its package versions do not necessarily track the latest Arch packages.
The crash is also rather time-intensive to reproduce, as it seems to only occur after at least an hour of playtime.

System information
Symptoms
At 11:50:02 MDT on 2026-09-03, the game triggered an AMDGPU GPUVM protection fault. Audio continued, but the display stopped updating. The GPU reset failed and Hyprland subsequently crashed. A forced shutdown was required.
Log files
Relevant journal excerpt:
The same GPU previously produced the same broad SQC-data GPUVM protection-fault class on 2026-06-26 while Chromium was running, but that incident recovered through an AMDGPU ring reset. No OOM condition was present.
Questions
The game is not officially supported on Linux. This report is intended to identify whether the D3D12 workload is being translated incorrectly or exercising an unsupported VKD3D/RADV path; it does not assume Capcom is responsible for a Linux fix.
