Symptoms

Game shows error message on start:

FATAL ERROR in Vertex Shader compilation
ShaderName: shdSwap

memory:67:22: error: syntax error, unexpected NEW_IDENTIFIER

at gml_Object_MetaCont_Draw_76

Reproduction

Every time starting the game.

Some players were getting same error on Windows and game developers added Beta version "shadertest" which works without problems on Proton.

Start by reviewing steam-1503530.log and reproducing the failure when launching Minit Fun Racer with Proton 5.13-6. Compare the failing default launch with the game's beta "shadertest" version, which reportedly works on Proton. Done would require identifying and resolving the Vertex Shader compilation error in shdSwap, but the report does not name a Proton source file or test.
