win32u: change the stretch mode of dst hdc from BlackOnWhite to ColorOnColor when using StretchBlt in TransparentBlt. In NtGdiTransparentBlt function, the StretchBlt mode of dst hdc is not set. The Default StretchBlt Mode in wine is BlackOnWhite. It is not correct to use this StretchBltMode in TransparentBlt dealing with color bitmap. According to MSDN, it should be converted to ColorOnColor. My test code shows that, the image converted by wine generates a lot of chromatic noise.

[PATCH v2 0/1] MR411: win32u: Don't load bitmap only TTF fonts without bitmap table.
by Paul Gofman (＠gofman) Oct. 12, 2025

Oct. 12, 2025

The offending font is NotoColorEmoji.ttf which is present in, e. g., google-noto-emoji-color-fonts or noto-fonts-emoji packages available in various distribution. Attempting to load this font on Windows 10 (with AddFontResourceA() or open it with default font viewer) fails while currently succeeds on Windows. fontforge also refuses to open this font. That is because the font is bitmap only but missing bitmap table. Some apps (Glyph launcher is an example) try to GetOutlineTextMetrics() on this font and do not expect that to have an error return (as we currenly do), which leads to crash on unhandled division by zero exception. I am attaching a bitmap-only ttf test font (with only one bitmap) which I created with fontforge to make sure that such font can still be loaded in Wine. This font also loads on Windows (both with AddFontResourceA() and with default font viewer). There are other font types which can be legitimately missing EBDT table, but FT_Load_Sfnt_Table() returns a different error for those and my patch doesn't reject those fonts.

[PATCH 0/1] MR6140: ntdll: Exclude biggest envars to fit 32767 chars limit in get_initial_environment.
by Martino Fontana (＠tinozzo123) Oct. 11, 2025

Oct. 11, 2025

Windows has a limit of 32767 characters in the environment block. https://superuser.com/questions/1070272/why-does-windows-have-a-limit-on-en… Wine doesn't attempt to respect that at all. Do some programs actually depend on this? Unfortunately yes. With this patch, during initialization, if the block size would exceed (or be close to) the limit, the biggest environment variables will be excluded. This is useful when a user has very long environment variables in their system for reasons unrelated to Wine. Do note that there's still nothing done to make sure that the limit isn't exceeded after initialization.

[PATCH v2 0/3] MR8760: mmdevapi: Add support for storing/retrieving more variant types from the device property store.
by Connor McAdams (＠cmcadams) Oct. 9, 2025

Oct. 9, 2025

This has been implemented in a few different ways (see MR !7238 and MR !359), neither of which have associated tests. This way of doing things sidesteps the need to update existing `VT_BLOB` properties by just storing/retrieving them in the same format we always have. If the registry data doesn't match a set of criteria, we treat it as `VT_BLOB` always. -- v2: mmdevapi: Add support for storing VT_CLSID properties. mmdevapi: Add support for storing VT_BOOL properties. https://gitlab.winehq.org/wine/wine/-/merge_requests/8760

[PATCH v2 0/8] MR8965: Draft: win32u: Flush window surfaces from owner thread, while waiting for messages.
by Rémi Bernon Oct. 9, 2025

Oct. 9, 2025

Instead of https://gitlab.winehq.org/wine/wine/-/merge_requests/8869 I think this would be a much lighter and less complicated approach than trying to wake the window threads with internal messages. And it should be able to avoid spurious wake ups when there's no window surfaces involved. What I'm not completely sure about is whether this is going to flush the surfaces frequently enough, and if we can assume the window thread will always either peek or wait for messages. -- v2: win32u: Keep window surfaces in a per-thread linked list. win32u: Remove window surface flush in expose_window_surface. win32u: Remove window surface flush on lock / unlock. win32u: Remove some less useful flush_window_surfaces. win32u: Flush window surfaces while waiting for messages. win32u: Use an absolute wait timeout in wait_message. win32u: Remove unnecessary window_surface exports. win32u: Dispatch NtUserUpdateLayeredWindow to the owner thread. https://gitlab.winehq.org/wine/wine/-/merge_requests/8965

[PATCH v7 0/8] MR8875: ntdll: Check signal access rights and notify when waiting on inproc queue.
by Rémi Bernon Oct. 9, 2025

Oct. 9, 2025

Later, a similar inproc sync as the queue will be created for user APC alerts and sent on thread init as well, saving us the need to special case those in the get_inproc_sync request and in the cache. -- v7: ntdll: Notify wineserver when waiting on inproc queue. ntdll: Add a reference count to inproc_sync objects. server: Create an inproc sync for message queue signaling. win32u: Move server queue handle to ntuser_thread_info. ntdll: Introduce a helper to wait on an server-side sync object. ntdll: Check inproc sync signal rights in signal and wait. server: Use a specific type for internal inproc event syncs. wineserver: Request RLIMIT_NOFILE maximum allowed value. https://gitlab.winehq.org/wine/wine/-/merge_requests/8875

[PATCH v3 0/4] MR7570: mfreadwrite: Implement encoder creation. (Part 1)
by Ziqing Hui (＠zhui) Oct. 9, 2025

Oct. 9, 2025

I split the implementations into 2 parts to make it looks easier to review. So plz first review this MR and make sure it's good so that we don't have to rebase. The follwing patches is in !7571. -- v3: mfreadwrite: Implement sink_writer_SetInputMediaType. mfreadwrite: Implement IMFSinkWriterEx. mfreadwrite: Add converter transform to stream. mfreadwrite: Add attributes member to writer struct. https://gitlab.winehq.org/wine/wine/-/merge_requests/7570

[PATCH v2 0/1] MR5213: Fix Cyberpunk 2077 spawning only one dispatcher thread in FreeBSD
by Katharine Chui (＠katharinechui) Oct. 8, 2025

Oct. 8, 2025

Normally Cyberpunk 2077 spawns #cpu_threads of dispatcher threads. However with Freebsd, since create_logical_proc_info was a stub, the game would instead spawn a single dispatcher thread, causing the game to just crawl. Working around the issue by adding a barebone implementation of create_logical_proc_info for FreeBSD so that the game would at least get a thread count through ntdll. -- v2: Fix Cyberpunk 2077 spawning only one dispatcher thread in FreeBSD https://gitlab.winehq.org/wine/wine/-/merge_requests/5213

[PATCH v4 0/3] MR9036: wined3d: Conditionally update saved window state in fullscreen mode.
by Matteo Bruni (＠Mystral) Oct. 8, 2025

Oct. 8, 2025

For Assassin's Creed Syndicate. When switching from fullscreen to a smaller windowed resolution, it calls `SetWindowPos()` centering the window, then calls `ResizeTarget()` and finally `SetFullscreenState()`, and expects the window to preserve the position. Window style handling is a bit iffy because of the manipulation we do when entering fullscreen, but that's not really new. -- v4: dxgi/tests: Test window states tracking and restoration in fullscreen mode. dxgi/tests: Use test contexts in test_resize_target(). wined3d: Conditionally update saved window state in fullscreen mode. https://gitlab.winehq.org/wine/wine/-/merge_requests/9036
