Game freezes repeatedly during play. In one 9.4 min session: 77 freeze events, ~336s total frozen (~60% of playtime). Doesn't happen on Windows on the same PC.

Every freeze is immediately preceded by a burst of this on one worker thread:
warn:vkd3d-proton:d3d12_resource_QueryInterface: {6b3b2502-6e51-45b3-90ee-9884265e8df3} not implemented, returning E_NOINTERFACE.

During the freeze itself, no thread logs anything — full process stall, not just one subsystem.

Freezes seem to line up with other players joining the lobby (their hide-object model loading?), so possibly tied to resource/pipeline creation.

Tested proton-cachyos, UMU-Proton, GE-Proton, and Proton Experimental — same behavior on all.
