[PATCH v3 0/2] MR1321: Reject wic invalid formats
by Zhiyi Zhang (＠zhiyi) Oct. 21, 2025

Oct. 21, 2025

These invalid formats are rejected when creating WIC render targets. Otherwise, Wine may create a WIC render target with an unsupported format and in turn, will make testing IsSupported() method difficult. -- v3: d2d1: Test creating WIC bitmap render targets. d2d1: Reject unsupported formats when creating WIC bitmap render targets. https://gitlab.winehq.org/wine/wine/-/merge_requests/1321

[PATCH v8 0/2] MR8178: user32: Fix uiLengthDrawn calculation in DrawTextExW().
by JiangYi Chen (＠meshine) Oct. 18, 2025

Oct. 18, 2025

uiLengthDrawn should represent the number of characters that have been processed. However, the original implementation uses len (the count of displayed characters in the current line), which is not accurate. When text requires line breaks or special processing (such as adding an ellipsis), the actual number of processed characters may differ from the number of displayed characters. When the DT_CALCRECT flag is absent, len gets decremented to 0 during the drawing loop. Consequently, uiLengthDrawn becomes inaccurate since it relies on len's value for statistics. -- v8: user32: Fix uiLengthDrawn calculation in DrawTextExW(). user32/tests: Add some tests for uiLengthDrawn calculation in DrawTextExW(). https://gitlab.winehq.org/wine/wine/-/merge_requests/8178

[PATCH v11 0/1] MR6131: Extend bcp47langs.dll with GetUserLanguages
by Marius Schiffer (＠MariusSchiffer) Oct. 17, 2025

Oct. 17, 2025

This is an undocumented API used by some programs to fetch the user's selected languages. Example is Fusion360 (during its login process). Signature currently taken from here: https://stackoverflow.com/questions/63877075/what-is-the-right-way-to-get-t… (Maybe that stackoverflow answer is also why Fusion has implemented this...)

[PATCH 0/1] MR8931: winex11.drv: Fixing an issue where the window size was not saved after...
by Ivan Lyugaev (＠valy) Oct. 16, 2025

winex11.drv: Fixing an issue where the window size was not saved after switching from full-screen mode When switching from maximized window to windowed mode, the window retains the size of the entire screen. This bug is reproducible in xfce. Upon closer examination of the logs, I noticed that xfce was duplicating ConfigureNotify requests. The duplicate requests had the send_event=TRUE flag. These requests caused the window to resize incorrectly. The current implementation of wine uses the asynchronous ConfigureNotify event notification method - NtUserPosteMessage with the WM_WINE_WINDOW_STATE_CHANGED flag. I suggest returning to the synchronous method using Send_message. This bug is a regression. This issue first appeared in commit 0f1d999b, which moved the handling of GetWindowStateUpdates in win32u/message.c to the handle_internal_message function via NtUserPostMessage. I decided to revert the handling logic to before this patch was applied, adapting it to the current handling of GetWindowStateUpdates in win32u/message.c This solution was tested in xfce, mate, and a number of different programs. Everything worked correctly -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8931

[PATCH v3 0/1] MR8988: win32u: change the stretch mode of dst hdc from BlackOnWhite to ColorOnColor...
by Kun Yang (＠yangkun) Oct. 12, 2025

Oct. 12, 2025

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.
