[PATCH v5 0/2] MR9639: Fix the integration of PowerPoint add-in in MS Office 2016
by Ivan Lyugaev (＠valy) March 15, 2026

March 15, 2026

Encountered an issue with PowerPoint add-in integration. Reviewing the logs revealed the problem was due to the lack of CLSID lookup via the CurVer section and incorrect handling of the PARAMFLAG_NONE flag. A test was conducted in Windows to verify the handling of PARAMFLAG_NONE, PARAMFLAG_FIN, and PARAMFLAG_FOUT. Test class: ``` interface ITest : IDispatch { [id(1)] HRESULT TestMethod(BSTR* value); [id(2)] HRESULT TestMethodOut([out] BSTR* retVal); [id(3)] HRESULT TestMethodIn([in] BSTR* inVal); }; ``` Results in Windows: ``` --------TestMethod-------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethod] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodIn------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodIn] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodOut------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodOut] (null) Invoke returned: 0x00000000 ``` Results in Wine: ``` --------TestMethod-------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethod] (null) Invoke returned: 0x00000000 -------TestMethodIn------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodIn] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodOut------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodOut] (null) ``` Therefore, parameters with the PARAMFLAG_NONE flag are implied to be input parameters in Windows and are handled accordingly as PARAMFLAG_FIN. Added tests for the implemented changes. In the last two tests (their code is provided below), the CLSID is nullified in the guid_from_string function, which is why this test is left with a todo_wine tag. ``` clsid = CLSID_StdFont; hr = CLSIDFromString(L"MyApp.DocumentTest.3", &clsid); todo_wine ok(IsEqualCLSID(&clsid, &CLSID_StdFont), "Unexpected clsid %s.\n", wine_dbgstr_guid(&clsid)); clsid = CLSID_StdFont; hr = CLSIDFromString(L"MyApp.DocumentTest.5", &clsid); todo_wine ok(IsEqualCLSID(&clsid, &CLSID_StdFont), "Unexpected clsid %s.\n", wine_dbgstr_guid(&clsid)); ``` -- v5: combase: Implement CLSID lookup with CurVer fallback oleaut32: Fix parameter value loss in ITypeInfo_Invoke for byref parameters https://gitlab.winehq.org/wine/wine/-/merge_requests/9639

[PATCH v7 0/7] MR5665: For a CS_PARENTDC child use parent for visible region calculations.
by Dmitry Timoshkov (＠dmitry) March 12, 2026

March 12, 2026

These patches fix painting in an application that draws outside of a CS_PARENTDC child client area in its WM_PAINT handler. Comments and suggestions are welcome. -- v7: win32u: Don't clip update region to the window client rectangle. win32u: GetUpdateRect() should clip update rectangle to the window client area. win32u: GetUpdateRgn() should clip update region to the window client area. win32u: Clip PAINTSTRUCT.rcPaint to the window client area. server: Don't generate WM_PAINT messages for minimized windows. server: For a CS_PARENTDC child use parent for visible region calculations. server: If the being validated region covers whole window then validate everything. https://gitlab.winehq.org/wine/wine/-/merge_requests/5665

[PATCH 0/1] MR8462: mfmediaengine: Delay old presentation clearing until new toplogy was set.
by Bernhard Kölbl March 11, 2026

March 11, 2026

Shutting down the media source, while it is still in an active topology, causes Windows' media session to fully shut down. To avoid this, only clear the old presentation on release, shutdown or when a new topology was successfully set. (FWIW: This solution is definitely not the greatest) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8462

[PATCH v4 0/4] MR9973: Draft: conhost: add basic VT control sequence
by Thomas Csovcsity (＠thc13) March 6, 2026

March 6, 2026

This is a minimal approach to running MC in wineconsole and addresses https://bugs.winehq.org/show_bug.cgi?id=49780. Wineconsole thus supports basic CSI control sequences for: - SGR (Select Graphic Rendition) and - CUP (Cursor Position) ![mc-in-wineconsole-260126](/uploads/36ed70375b31955fa44dc477e832242c/mc-in-wineconsole-260126.gif){width=900 height=507} **TODO:** - [x] check for ENABLE_VIRTUAL_TERMINAL_PROCESSING - [x] bug states that SetConsoleMode does not return error code and therefore applications fail to handle it correctly - [ ] rewrite, if that is the way to go i will do that, to use newer API. This would allow more colors than ANSI colors only - [ ] test shared: several programs attached to the same console -- v4: conhost: add basic CUP color handling conhost: improve basic SGR color handling conhost: add basic SGR color handling conhost: add basic VT control sequence parsing https://gitlab.winehq.org/wine/wine/-/merge_requests/9973

WaitCompletionPacket is a kernel object that, when associated with a target object and a completion object and when the target object is signaled, adds the completion information stored in itself to the completion object.

[PATCH v2 0/2] MR9857: ntdll/unix: Reimplement fill_vm_counters() for macOS.
by Jactry Zeng (＠jactry) March 5, 2026

March 5, 2026

On Windows, PagefileUsage represents the total private memory committed by a process, includes both resident memory in RAM and pages swapped to the disk. On macOS, virtual_size is misleading as it represents the total reserved address space, which is often vastly larger than actual usage; for example, it can be 40+GB when a program was alloced about 4GB memory on a machine with 16GB RAM (tested on Intel macOS 15.7.2 and Apple Silicon macOS 26.2). In order to make it closer to the Windows metric, using the sum of TASK_VM_INFO.internal (resident private memory in RAM) and swapped pages (includes both compressed memory in RAM and pages that were swapped to the disk) from mach_vm_region_recurse() is more correct. I also use the sum of TASK_VM_INFO.internal and TASK_VM_INFO.compressed (compressed memory, and still in RAM) as a fallback when mach_vm_region_recurse() fails; however, this doesn't include that the memory has been compressed and swapped to the disk[0], but it is still correct relatively to the current implementation.

[PATCH v2 0/6] MR9348: comctl32/imagelist: Pre-multiply rgb by the alpha channel in add_dib_bits for v6.
by Ziqing Hui (＠zhui) March 3, 2026

March 3, 2026

We used to do this when drawing the image. But our tests show that for v6, the image bitmaps have been alpha pre-multiplied before drawing. So we should do this when adding images. -- v2: comctl32/imagelist: Support adding 32bpp images to a non-32bpp image list for v6. comctl32/imagelist: Do alpha blending when adding 32bpp images to a non-32bpp image list. comctl32/imagelist: Introduce create_dib_section helper. comctl32/imagelist: Introduce image_list_color_flag helper. comctl32/imagelist: Pre-multiply rgb by the alpha channel in add_dib_bits for v6. comctl32/imagelist: Introduce premultiply_alpha_channel helper. https://gitlab.winehq.org/wine/wine/-/merge_requests/9348
