[Bug 59436] New: Wayland/EGL: Washed-out colors caused by double sRGB conversion on default framebuffer (GL_FRAMEBUFFER_SRGB)
by WineHQ Bugzilla July 26, 2026

http://bugs.winehq.org/show_bug.cgi?id=59436 Bug ID: 59436 Summary: Wayland/EGL: Washed-out colors caused by double sRGB conversion on default framebuffer (GL_FRAMEBUFFER_SRGB) Product: Wine Version: 11.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winewayland Assignee: wine-bugs(a)list.winehq.org Reporter: tpaniaki(a)protonmail.com Distribution: --- Created attachment 80417 --> http://bugs.winehq.org/attachment.cgi?id=80417 Patch Fixes https://bugs.winehq.org/show_bug.cgi?id=59073 Summary When running Wine with the Wayland driver (winewayland.drv) using EGL, colors may appear washed out / desaturated in OpenGL applications. The issue is caused by GL_FRAMEBUFFER_SRGB remaining enabled while rendering to the default framebuffer (FBO 0), leading to a double gamma/sRGB conversion in some Wayland/EGL pipelines. Disabling GL_FRAMEBUFFER_SRGB only when rendering to the default framebuffer fixes the color output. Environment Wine: wine-git (tested on 11.x, reproducible on current master) Backend: winewayland.drv (Wayland native, not XWayland) GPU: AMD (Mesa) Compositor: wlroots-based (qtile Wayland) EGL backend in use Application tested: Roon (Chromium/CEF-based UI, OpenGL rendering) Observed behavior Colors appear faded / washed out Gamma looks incorrect (as if double sRGB conversion occurs) Issue only occurs under Wayland/EGL Colors are correct: Under X11/XWayland Or if GL_FRAMEBUFFER_SRGB is manually disabled for FBO 0 Root cause hypothesis Some Wayland/EGL compositors already perform colorspace handling for the window surface. If GL_FRAMEBUFFER_SRGB remains enabled when rendering to the default framebuffer, the pipeline applies sRGB conversion twice: App → GL_FRAMEBUFFER_SRGB → EGL/Compositor colorspace → Display This results in desaturated output. Minimal fix Disable GL_FRAMEBUFFER_SRGB only when binding the default framebuffer (FBO 0), while preserving the application's requested sRGB state for non-default FBOs. Example patch (conceptual) Inside framebuffer binding path: if (!framebuffer && gl_info->supported[ARB_FRAMEBUFFER_SRGB]) { TRACE("glBindFramebuffer disabling GL_FRAMEBUFFER_SRGB on default framebuffer\n"); glDisable(GL_FRAMEBUFFER_SRGB); } else if (framebuffer && app_framebuffer_srgb_enabled) { TRACE("glBindFramebuffer restoring GL_FRAMEBUFFER_SRGB on non-default framebuffer\n"); glEnable(GL_FRAMEBUFFER_SRGB); } Results Colors become correct under Wayland/EGL No regression observed in tested OpenGL apps Behavior matches X11 output sRGB still works correctly for offscreen FBO rendering -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59834] New: WoW64: int 2Eh instruction in 32-bit code causes #GP that isn't forwarded to 32-bit exception handler
by WineHQ Bugzilla July 25, 2026

July 25, 2026

http://bugs.winehq.org/show_bug.cgi?id=59834 Bug ID: 59834 Summary: WoW64: int 2Eh instruction in 32-bit code causes #GP that isn't forwarded to 32-bit exception handler Product: Wine Version: 11.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)list.winehq.org Reporter: vonvontabang(a)gmail.com Distribution: --- Created attachment 81114 --> http://bugs.winehq.org/attachment.cgi?id=81114 Full crash log with WoW64 int 2Eh SEH chain, register dumps, backtrace, and analysis across 6 Proton/Wine builds Summary: WoW64: int 2Eh instruction from 32-bit shellcode causes #GP that isn't forwarded to 32-bit exception handler Description: Under Wine's WoW64 (x86_64 guest i386), a 32-bit process executing raw syscalls via int 2Eh (bytes CD 2E) raises a #GP that is delivered as SIGSEGV. While Wine correctly converts this to EXCEPTION_ACCESS_VIOLATION and dispatches through the SEH chain, the underlying issue is that WoW64 has no handler for privileged instructions executed from 32-bit compat mode (CS=0023). Crash signature (consistent across all WoW64 builds): EXCEPTION_ACCESS_VIOLATION (0xc0000005) EAX = <shellcode RWX base> (e.g. 008D0000) EDX = 0x8 (syscall number) ECX = 0xE9000001 (syscall argument) CS = 0023 (32-bit compat mode under WoW64) EIP = <base>+0x6/0x7/0xF (offset into shellcode) Affected builds: Proton Experimental, Proton-EM, DW-Proton, Proton-CachyOS, GE-Proton10-34, system Wine 11.10 — all WoW64. The same shellcode also crashes intermittently on native Windows (server switches, elevated apps, PC lock), confirming a latent bug in the xtrap/AegisAC anti-cheat shellcode exposed 100% of the time under Wine WoW64. Root cause: Wine's WoW64 layer needs to either route int 2Eh syscalls to the 64-bit ntdll (as Windows WoW64 does), or at minimum provide a graceful error instead of crashing.
