Thanks for regression bisect.

Regression only affects OpenGL renderer, per commit details.

Vulkan backend for vanilla WINE renders graphics for both games, enabled via:
winetricks renderer=vulkan

Both games seem to run on Vulkan consistent with OpenGL renderer prior to
regression.

Gameplay lag for Vulkan seems to match OpenGL lag.

Signifier video also still not playing for Vulkan as for OpenGL.
