[PATCH 0/1] MR9253: winemac.drv: Create window data for message-only windows.
by Tim Clem (＠tclem) 03 Nov '25

03 Nov '25

Their surfaces may be used. --- x11drv already supports this (and we test for it in opengl32/tests/opengl.c:test_message_window). x11drv doesn't make an x11drv_win_data for message-only windows when they are initially created in X11DRV_create_win_data, but does later if a surface is requested (x11drv_client_surface_create -> create_client_window). I don't see much of a reason to do it lazily in macdrv. We won't make a Cocoa window for message-only windows in macdrv_create_win_data since the parent isn't the desktop, so we're really just allocating space for the macdrv_win_data. And plus opengl.c:macdrv_surface_create uses `get_win_data(hwnd)` as its check for whether a hwnd is in-process; we'd have to adjust that logic (and shuffle some things around in that function) if we were to have macdrv_client_surface_create potentially create a macdrv_win_data. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9253

[PATCH 0/1] MR9343: windowscodecs: Fix potential integer overflow in PNG format reader
by Wei Xie (＠wayne) 03 Nov '25

03 Nov '25

Fixed a potential integer overflow issue in the read_ulong_be function by adding an explicit cast to ULONG before bit shifting. The data[0] byte was being shifted left 24 bits without proper casting, which could cause overflow when the byte value is large and the compiler treats it as a signed char. This ensures proper 32-bit unsigned integer behavior during the bitwise OR operations. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9343

[PATCH 0/1] MR9344: d2d1: Fix incorrect union member access in radial gradient brush
by Yeshun Ye (＠yeyeshun) 03 Nov '25

Fixed union member misuse in d2d_brush_fill_cb() function where radial gradient brush processing incorrectly accessed brush->u.linear.gradient instead of brush->u.radial.gradient. Signed-off-by: YeshunYe <yeyeshun(a)uniontech.com> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9344

[PATCH v2 0/2] MR9323: user32: Fix loading comctl32 v5 after comctl32 v6 is loaded.
by Zhiyi Zhang (＠zhiyi) 03 Nov '25

03 Nov '25

When comctl32 v6 is loaded and v6 manifest is disabled, comctl32 v5 should be used when creating a common control window. However, before this patch, GetModuleHandleW(L"comctl32") return a handle to comctl32 v6 in this case, so comctl32 v5 doesn't get loaded and creating comctl32 v5 windows fails. We need to check if comctl32 v5 is actually loaded by using GetModuleHandleW() with the absolute path of the comctl32 v5 dll. Fix Word 2010 file open dialog doesn't show a listview. -- v2: comctl32: Use a magic value to check if an image list is valid. comctl32/tests: Test image list interoperation with comctl32 v5 and v6. https://gitlab.winehq.org/wine/wine/-/merge_requests/9323

[PATCH v4 0/9] MR8812: winegstreamer: Support 2D sample buffer.
by Conor McCarthy (＠cmccarthy) 03 Nov '25

03 Nov '25

Performance issues can occur when a video output sample has a 2D buffer, because winegstreamer currently outputs only to a linear buffer, which must then be copied into the 2D buffer. Worse, a linear lock of the 2D buffer requires the current contents to be copied to a linear buffer, even when we intend to overwrite it, because MF linear buffers do not support write-only locking. -- v4: mf/tests: Test H.264 sink media type height alignment. winegstreamer: Support 2D sample buffer. mf: Test color convert 2D buffers. mf: Test WMV decoder 2D buffers. mf: Test H.264 decoder 2D buffers. mf: Test sample copier 2D buffers. mfplat/tests: Test NV12 negative stride in MFCreateMediaBufferFromMediaType(). mf/tests: Remove todo for an H.264 decoder test. mf/tests: Stop checking samples at the end of the expected array. https://gitlab.winehq.org/wine/wine/-/merge_requests/8812

Re: [PATCH v5 0/6] MR9032: opengl32: Support wow64 buffer storage and persistent memory mapping using Vulkan.
by Re-a (＠Liverel) 03 Nov '25

03 Nov '25

I have a laptop that supports up to OpenGL 4.2 and Vulkan 1.2, and also another laptop that supports OpenGL 4.6 and Vulkan 1.2, and still fix doesn't work on both laptops. Wine still falls back to the slow mapping; you can see it in the logs. What am I missing? Is there going to be an alternative that works on more systems at some point? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9032#note_120407
