Symptoms

The game either get's stuck on the opening screen with nothing but the cursor displayed, or, if Direct X 11 is used via proton command, the game will crash instantly and give the error shown in the pastebin here https://pastebin.com/fkAAzgJC . It seems to be an issue with the way the mfplat is implemented into both WINE and Proton.

Reproduction

Run the game without any special commands, or with DX11 forced via proton variable.

Start by reviewing steam-803600.log and the linked pastebin error alongside Proton 3.16-3 and the reproduction steps. Compare behavior with and without DX11 and inspect the reported mfplat/WINE context; done means Disgaea 5 Complete reaches the opening screen without the described crash or hang.
