Bug ID: 59033
           Summary: OpenGL applications fail to start under EGL backend
           Product: Wine
           Version: 10.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: opengl
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Tested with Touhou Fuujinroku (Mountain of Faith), running via THCRAP and with
vpatch.
Also tested with Bejeweled 3.

Games run fine when the EGL backend is disabled via UseEGL=0 in the registry,
but OpenGL initialization completely fails when enabled (the default since
10.17).

Curiously, the error happens to be different every time; sometimes context
creation fails completely and the entire process hangs until wineserver -k,
sometimes the X11 error is shown and the application exits immediately,
sometimes getting pixel formats fails but the process can resume.

I hacked on the code a bit to get some more information, and I get an
NT_ACCESS_VIOLATION from the first UNIX_CALL `get_pixel_format` on the PE side.

Attached are logs with WINEDEBUG=trace+opengl.

System information:

OS: Gentoo Linux amd64
Kernel version: 6.17.7-gentoo
Wine version: wine-10.19
Wine backend: X11
Mesa version: 25.3.0
Graphics card: AMD Radeon RX 6700 XT
Desktop environment: Hyprland 0.51.1 + xwayland 24.1.9

I am not sure if it is related but I believe it is, because modifying some
settings related to the render system allowed me to run apps temporarily.

Specifically a problem with RPG Maker MV games. (RPG Maker MZ, as well as old
engines work fine)

Operating System: Arch Linux 
Kernel Version: 6.17.8-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 7800X3D 8-Core Processor
Memory: 64 GiB of RAM (62.4 GiB usable)
Graphics Processor: AMD Radeon RX 7900 XT
Wine Version: 10.19 (wow64 mode)

This only started happening on the current version. The game in question
immeditately loads the window and then before anything is rendered, the game
crashes.

The debug logs from the engine itself are filled with the following:

[1125/112338.241:ERROR:http_transport_win.cc(175)] WinHttpCrackUrl: error 0x13d
while retrieving error 0x2ee6

I do not believe this is related, as I think it has something to do with the
bug reporter tool, but I am including it anyway.

I will be attaching my error trace, both with EGL enabled and disabled.
