Bug ID: 57018
           Summary: Japanese adult Pixel Game Maker game has white screen
           Product: Wine
           Version: 9.13
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The game can be downloaded from dlsite (NSFW):
https://trial.dlsite.com/doujin/RJ364000/RJ363962_trial.zip

Just download and extract the demo. Make sure the folder and exe don't have
garbage characters - just rename them to anything, if necessary. Or extract
them with japanese locale to begin with.

Run the game, in the main menu you can navigate with arrow keys and confirm
with "Z". On German keyboard that is the "Y" key though.

Select new game. You get a white screen, you can press the arrow keys to
navigate up and down though, so it's not frozen but doesn't render.

The program seems to use OpenGL. I can confirm the game works on windows (AMD
driver).

I made an apitrace on Linux, and during playback it fails with
> major shader compiler error 5: 0:32(15): error: could not implicitly convert operands to arithmetic operator

However, the same apitrace doesn't work under windows or on Linux with
proprietary AMD drivers.

Unfortunately, making an apitrace under Windows doesn't work, it doesn't manage
to hook.

In short, I think this might be a driver issue, but I'm not sure.

Created attachment 76863

Replacement shader

Using the attached replacement shader with MESA_SHADER_READ_PATH makes it work

...maybe it's just my distro, but unzip does have a parameter for passing the
codepage to use while unpacking.

Forget to mention, but I only changed one line, it was originally:
> texColor *= (1 - Intensity);
