Research direction

Start by reviewing steam-25800.log and the linked Wine bug 37676, focusing on the unsupported fx_2_0 shader compilation reported for Europa Universalis III. Reproduce the single-frame crash with Proton 5.0-3 if the environment is available; done means the game progresses past the crash without that shader-compilation failure.
