[PATCH 0/2] MR9748: Draft: msi: Implement MsiProvideAssemblyW().
by Dmitry Timoshkov (＠dmitry) May 7, 2026

May 7, 2026

While bug 58578 depends on MsiProvideAssemblyW() my testing target is SQL Server Express 2012 (bug 42792 has a download URL). I marked this MR as a draft because the implementation doesn't seem to work: MsiProvideComponent() detects feature INSTALLSTATE_ABSENT, MSDN mentions that both MsiProvideAssembly() and MsiProvideComponent() should return ERROR_FILE_NOT_FOUND in that case, however the installer generates an exception and crashes once this error is returned. The installer calls MsiProvideAssembly() with the application context, however I investigated with Orca the problematic MSI and for the assembly specified in the MsiProvideAssembly() call there's no associated application, so it's not clear how it's supposed to behave in that case. Hans, would you mind looking at this and probably suggest the ways to proceed? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9748

[PATCH v5 0/2] MR7938: Draft: winemac: Use IOSurface to update native window layers instead of CGImage.
by Marc-Aurel Zent (＠mzent) May 6, 2026

May 6, 2026

This consolidates the two separate `CGImage`s (`colorImage` and `shapeImage`) previously used in `WineContentView` into a single `IOSurface` that also holds the window mask information in its alpha channel now. The alpha channel is now being updated in `macdrv_surface_flush`, whenever the shape changes (and stores that change for the next update, to also keep the front buffer in sync). This reduces the delay from setting a `CGImage` to a layer from 50ms to about 1.5ms in the `IOSurface` case (also accounting for `vImageSelectChannels_ARGB8888` operation). Based on a patch by @bshanks. I am already putting it out for feedback, but I will so some more testing to see how the performance impact of this is and do more exhaustive testing with shaped windows. Ideally the double buffer solution can be avoided as well... Also the `HBITMAP` for the windows is currently backed by a `CGDataProviderRef` and could also become an `IOSurface` I believe. -- v5: winemac: Use IOSurface to update native window layers instead of CGImage. https://gitlab.winehq.org/wine/wine/-/merge_requests/7938

[PATCH 0/2] MR6841: wow64: Support running a BT module provided suspend routine.
by Billy Laws (＠bylaws) May 4, 2026

May 4, 2026

Suspension in JITs cannot easily be handled on the unix side, so allow BT modules to provide their own suspend helper. This purely supports local thread suspension currently. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6841

[PATCH v12 0/1] MR9840: winepulse.drv: A potential solution to audio crackling
by Dzmitry Keremsha (＠Vyrolian) April 30, 2026

April 30, 2026

I have noticed that winepulse leaves too little headroom when draining the buffer, which very often leads to crackling that can't be fully resolved by manipulating latency. Let's check some math: Let's assume that the buffer (tlength) is at 33ms, and minreq is at 13.3ms. If 13.2 ms were drained, the refill would be denied. If the next timer trigger takes 14ms due to jitter, that leaves us with a 6.1ms margin. As such, if we get any jitter longer than that during refill, we get an underflow. I think this is what leads to crackles. My solution increases timer polling to 5x the frequency, so if 13.2ms were drained, the next timer trigger would happen at around 16ms. That would leave us with a 17ms headroom. The math might not be 100% representation of what happens, but I think it's quite close to reality. On practice, this does indeed help to fully get rid of crackling for an indefinite amount of time, when before they were unevitable. I think this problem is quite urgent, because while this does not happen on every system, it's frequent enough that we see "Audio: Crackling" reports on most games on protondb and there are many forum threads about audio crackling. From my experience, the only solution was switching to winealsa, which is very consistent and does not crackle at all. My experience has been very consistent with forum threads when it came to the nature of crackling. I first noticed it in Balatro, which is a very light game and should not be crackling at all on any setup. Some games have very frequent crackling every 20-30 seconds, or buzzsaw crackling every 10-15 minutes. I hope my idea brings us closer to the ultimate fix, I really look forward to your feedback! -- v12: winepulse.drv: Increase timer frequency https://gitlab.winehq.org/wine/wine/-/merge_requests/9840

[PATCH 0/2] MR8414: Fix EV Nova game text truncation.
by Zhiyi Zhang (＠zhiyi) April 29, 2026

April 29, 2026

Fix the rectangle from DrawText(..., DT_CALCRECT) with a selected font might not be enough to actually draw text with the font for the EV Nova game. This ensures that text extent calculated with a font selected in a device context is enough when drawing texts using the same font and device context. The root cause is that FreeType might report different font metrics for different GGO formats. GetTextExtentExPoint() gets text extent with GGO_METRICS. And GGO_METRICS gets font metrics from glyphs loaded with FT_LOAD_TARGET_NORMAL, so when drawing bitmap fonts, which is of GGO_BITMAP format loaded with FT_LOAD_TARGET_MONO, with the calculated text extent, the result text might get truncated because of the font metrics difference. On Windows, anti-aliased font and bitmap font of the same face font reports the same font metrics so such a problem doesn't happen. The ultimate fix is to let FreeType hint the bitmap fonts with the same font metrics as anti-aliased fonts but there are no settings that can achieve it unless we write a new FreeType hinter.

[PATCH v4 0/1] MR8794: shell32: Restore the ability of running unix executables via unix paths
by Yuxuan Shui (＠yshui) April 17, 2026

April 17, 2026

MobaXTerm tries to ShellExecute "/bin/sh" when running under wine. This ability to run unix executables on the host via unix paths was accidentally removed in the attemp to align ShellExecute more closely with native, while fixing the problem that sometimes wrong executable is started by ShellExecute (e.g. in Motor Race Collection).
