Symptoms

The Game starts normally it displays some logos at startup and a loading screen, then after the loading screen the game should show the main menu but it displays only a blank white screen. from the sound you can still navigate the menu and even start the game but the white screen will not disappear.
Previous entries in the Atelier series had a problem at startup with resource sharing which was solved by a d3d9.dll dummy but this fix simply causes the game to crash when the main menu (and the white screen bug) would normally appear.

I couldn't upload the logs as they are because the one without the dummy dll is 190mb big and the one with the dummy dll is 150mb big, i hope packing them as a zip file won't cause issues.

Reproduction

Just start the game and watch the logos and the loading screen and there the bug should appear.

Start by reproducing the blank white screen after the loading screen on Proton 4.2-4, then inspect the attached steam-1045620log.zip and compare behavior with and without the d3d9.dll dummy. Done means the game reaches and visibly renders its main menu and gameplay without the workaround causing a crash.
