http://bugs.winehq.org/show_bug.cgi?id=59033 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: wine-bugs(a)list.winehq.org Reporter: sin-ack(a)protonmail.com 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 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
