[Bug 59506] New: IMFMediaEngine video playback fails: no MFT_CATEGORY_VIDEO_PROCESSOR registered for NV12→RGB32 color conversion
by WineHQ Bugzilla July 29, 2026

http://bugs.winehq.org/show_bug.cgi?id=59506 Bug ID: 59506 Summary: IMFMediaEngine video playback fails: no MFT_CATEGORY_VIDEO_PROCESSOR registered for NV12→RGB32 color conversion Product: Wine Version: 11.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: mfplat Assignee: wine-bugs(a)list.winehq.org Reporter: Loong.0x00(a)gmail.com Distribution: --- IMFMediaEngine video playback fails because no MFT_CATEGORY_VIDEO_PROCESSOR transform is registered to handle color space conversion (NV12 → RGB32). On Windows, the Color Converter DSP (CLSID_CColorConvertDMO) handles this. Wine does not register any equivalent MFT in this category. == Failure chain (traced with WINEDEBUG=+mf,+mfplat,+mfmediaengine) == 1. IMFMediaEngine::SetSourceFromByteStream("video.mp4") → OK 2. Source resolver creates media source from byte stream → OK 3. topology_loader_Load runs (real implementation, not a stub despite FIXME string) 4. MFTEnumEx(MFT_CATEGORY_VIDEO_DECODER, H264) → finds h264_decoder, activates OK 5. GStreamer pipeline: h264parse → avdec_h264 → videoconvert, all linked successfully 6. H264 decoder outputs NV12 7. video_frame_sink expects RGB32 (MFVideoFormat_RGB32, GUID {00000020-0000-0010-8000-00aa00389b71}) 8. MFTEnumEx(MFT_CATEGORY_VIDEO_PROCESSOR, NV12→RGB32) → returns 0 results ← ROOT CAUSE 9. topology_branch_connect returns 0xc00d5212 (MF_E_TRANSFORM_NOT_POSSIBLE) 10. session_set_topology fails with 0xc00d36b9 (MF_E_TOPO_UNSUPPORTED) 11. MEError 0xc00d3e85 (MF_E_TOPO_CODEC_NOT_FOUND) propagated to application == Additional stubs == IMFMediaEngineEx::SetAutoPlay() and SetLoop() store the flag internally but the playback engine never consumes it, so video looping does not work. == Affected application == Wallpaper Engine (Steam AppID 431960). Scene wallpapers with embedded video textures use IMFMediaEngine::SetSourceFromByteStream() to decode .mp4 files as texture layers. All such wallpapers fail with grey/blank video layers. == Relevant trace excerpt == topology_loader_Load iface ..., input_topology ..., ret_topology ..., current_topology 0x0 stub!

[Bug 59334] New: Pop-up menu opened behind the parent window in Steam when using XWayland in full-screen mode
by WineHQ Bugzilla July 29, 2026

July 29, 2026

http://bugs.winehq.org/show_bug.cgi?id=59334 Bug ID: 59334 Summary: Pop-up menu opened behind the parent window in Steam when using XWayland in full-screen mode Product: Wine Version: 11.1 Hardware: x86-64 URL: https://cdn.fastly.steamstatic.com/client/installer/St eamSetup.exe OS: Linux Status: NEW Keywords: download Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: gyebro69(a)gmail.com Distribution: ArchLinux Created attachment 80272 --> http://bugs.winehq.org/attachment.cgi?id=80272 plain terminal output In the Steam client, when you right-click a game in your library, a context menu opens that allows you to perform several functions, such as uninstalling, performing a validity check, or viewing properties. This context menu opens behind the main Steam window; therefore, it cannot be interacted with. This happens when running Steam in XWayland and using Wine full-screen mode. In XWayland and virtual desktop mode the menu appears correctly. The problem doesn't occur under X Server and using full-screen (XFCE). I also reproduced the issue in Weston 14.0.2; this rules out the possibility of it being a bug specific to KDE Plasma or KWin as far as I know. I can't check out the native Wayland driver because it has it's own problem: the Steam window is empty/black using Wayland. The same problem with Wine-9.0, 10.0 etc. Wine-Staging has this problem, too. You can reproduce the problem even though you don't have a Steam account. Install the Steam client, let it perform the auto-update and when the login window appears click on <Create a free account> in the lower right corner. There is a drop-down menu under Country of residence, when opened in full-screen mode (XWayland), the list of countries appear behind the main Steam window. In virtual desktop mode the list is visible properly. wine-11.1-102-g93f3d8ae9fa Arch Linux KDE Plasma 6.5.5 KWin (Wayland) Xwayland Version 24.1.9 Nvidia binary drivers 590.48.01 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58921] New: WebView2 does not work with Windows version setting 8.1 or newer

http://bugs.winehq.org/show_bug.cgi?id=58921 Bug ID: 58921 Summary: WebView2 does not work with Windows version setting 8.1 or newer Product: Wine Version: 10.18 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: felixhaedicke(a)web.de Distribution: --- Created attachment 79605 --> http://bugs.winehq.org/attachment.cgi?id=79605 webview.log (log created by WebView2) For testing WebView2, I am using my "SimpleWebView2Browser", see https://github.com/felixhaedicke/SimpleWebView2Browser for source code and binaries. Steps to get it running on a fresh wineprefix: * Install WebView2 runtime using the "Evergreen Standalone Installer" for x64 from Inst https://developer.microsoft.com/en-us/microsoft-edge/webview2 * Set Windows version to Windows 7 or 8. * Use my "SimpleWebView2Browser" binaries from https://github.com/felixhaedicke/SimpleWebView2Browser/releases/tag/v0.1 It is sufficient to set the Windows version for "msedgewebview2.exe" (which is part of the WebView2 runtime): wine reg add "HKEY_CURRENT_USER\Software\Wine\AppDefaults\msedgewebview2.exe" /v Version /t REG_SZ /d win8 It does not work with Windows version set to 8.1, 10 or 11. The problem is probably that WebView2 tries to use the DirectComposition API on Windows 8.1 or newer. Message in the WebView2 debug log: DCompositionCreateDevice failed: Not implemented. (0x80004001) The attached WebView2 debug log was captured using the WebView2 logging functions, which can be enabled using the WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS environment variable.

[Bug 58325] New: wined3d swapchain use-after-free
by WineHQ Bugzilla July 28, 2026

July 28, 2026

http://bugs.winehq.org/show_bug.cgi?id=58325 Bug ID: 58325 Summary: wined3d swapchain use-after-free Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: d3d Assignee: wine-bugs(a)winehq.org Reporter: yshuiv7(a)gmail.com Distribution: --- Releasing the swapchain brings us to wined3d_swapchain_cleanup, which destroys the front/back buffer textures. Texture destruction is async, happening on the device's command stream. This means these textures can be destroyed way after the swapchain itself. But we did set `texture->swapchain` to `NULL` before queuing their destruction, so that bit is fine. The problem is in texture_resource_unload. Here we try to acquire the context, which goes adapter_gl_acquire_context -> wined3d_context_gl_acquire -> wined3d_context_gl_activate -> wined3d_context_gl_update_window. And here we try to access `context_gl->c.swapchain->win_handle`, which unfortunately points to the swapchain that was just freed. I am unsure what's the fix for this. Do we hold a refcount of the swapchain in the context? Do we clear `context->swapchain` when a swapchain is being freed? Should we release the front/back buffer synchronously? Or something else? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
