Bug ID: 58832
           Summary: Grey screen in Elasto Mania II on Wine 10.17
           Product: Wine
           Version: 10.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ArchLinux

I am using an offline installer downloaded from GOG.com for Elasto Mania II.
Version is listed as 1.02 and the file is named
setup_elasto_mania_ii_1.02_(57739).exe

I setup the game in a fresh prefix by running:
WINEPREFIX=$PWD/wine/elma2 wine "setup_elasto_mania_ii_1.02_(57739).exe"

Installer runs fine and the game is installed. Then if I click "Launch" in
setup wizard, the game is launched in full screen and the whole screen is grey.
Terminal is flooded with messages:
libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering.

Then I disable EGL by running
WINEPREFIX=$PWD/wine/elma2 wine reg add "HKCU\Software\Wine\X11 Driver" /v
UseEGL /d N /f

If I launch the game via menu
("~/.local/share/applications/wine/Programs/Elasto Mania II [GOG.com]/Elasto
Mania II.desktop" file is created during setup), the game runs fine.

I then do
WINEPREFIX=$PWD/wine/elma2 wine reg delete "HKCU\Software\Wine\X11 Driver"
/v UseEGL /f
and launch the game again via the menu: there is only grey screen.

This started after updating Wine to 10.17 on my Arch Linux system. As I see in
release notes for 10.17 EGL has been enabled by default, this is why I tried to
disable it and it worked: https://www.winehq.org/news/2025101701

Thanks for the report! This is likely a duplicate of bug 58812 which has just
been fixed with commit 63e6cfa106a0b12351e8d01eb5bfefd925c3a74e (not in Wine
10.17).

I also tested with Wayland by setting:
WINEPREFIX="$PWD/wine/elma2" wine reg.exe add HKCU\Software\Wine\Drivers /v
Graphics /d wayland

Apparently then EGL is always used, reconfiguring UseEGL for "X11 Driver"
unsurprisingly does not change anything. Xwayland is not started and I always
get the same grey screen.

Yes, the Wayland driver suffers from the same issue but doesn't have any
fallback like GLX for X11. Then the same commit should fix front buffer
rendering for the Wayland too.
