[Bug 59610] New: X11 pointer grab breaks on XWayland after closing a dropdown in a dialog over a fullscreen window
by WineHQ Bugzilla April 3, 2026

April 3, 2026

http://bugs.winehq.org/show_bug.cgi?id=59610 Bug ID: 59610 Summary: X11 pointer grab breaks on XWayland after closing a dropdown in a dialog over a fullscreen window Product: Wine Version: 11.5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: lldmakhbfcrmqyluns(a)nesopf.com Distribution: --- ystem: Kubuntu 25.04, KDE Plasma 6 (Wayland), KWin 6.4.5, Wine 11.5 devel. Symptoms: When running a Windows application in fullscreen mode under XWayland, opening and closing a combobox (dropdown list) inside a modal dialog causes all subsequent mouse clicks in that dialog to be ignored. Keyboard navigation (Tab/Space) still works. The issue does NOT happen in windowed mode. Steps to reproduce (using FastStone Image Viewer as an example): Open an image in FSViewer and press 'F' to enter Fullscreen. Press Ctrl+R to open the "Resize" dialog. Click on any combobox (e.g., the "Filter" dropdown) to open the list, then click to close it or select an item. Try to click the "OK", "Cancel" or any other button with the mouse. Clicks are completely ignored. Investigation & Workaround: The issue is caused by a conflict between Wine's XGrabPointer (used for fullscreen ClipCursor) and XWayland/KWin surface restacking when the override_redirect window of the combobox is destroyed. The grab is not properly restored/respected by the compositor, and ButtonPress events are lost. Setting the following registry keys completely fixes the issue: HKCU\Software\Wine\X11 Driver\GrabFullscreen = "N" HKCU\Software\Wine\X11 Driver\GrabPointer = "N" Suggested fix: Wine should probably avoid strict XGrabPointer for non-gaming fullscreen applications under XWayland, or detect XWayland and rely on Wayland pointer constraints instead, as X11 grab emulation in Wayland compositors is prone to state desyncs during popup creation/destruction. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59608] New: wined3d: D3DRS_ALPHATESTENABLE has no effect on GLES-derived GL drivers (Panfrost) in compat profile — alpha-tested geometry renders opaque
by WineHQ Bugzilla April 2, 2026

April 2, 2026

http://bugs.winehq.org/show_bug.cgi?id=59608 Bug ID: 59608 Summary: wined3d: D3DRS_ALPHATESTENABLE has no effect on GLES-derived GL drivers (Panfrost) in compat profile — alpha-tested geometry renders opaque Product: Wine Version: 11.4 Hardware: aarch64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: d3d Assignee: wine-bugs(a)list.winehq.org Reporter: siordache94(a)gmail.com Distribution: --- When running a Direct3D 9 application on a GLES-derived OpenGL driver (Mesa Panfrost, Mali-G52) with MESA_GL_VERSION_OVERRIDE=3.1COMPAT, D3DRS_ALPHATESTENABLE render state changes have no visible effect. Alpha-tested geometry (e.g. billboard tree cards using DXT3 textures with alpha) renders as fully opaque solid rectangles instead of having transparent pixels discarded. ### Environment - Wine 11.4 (ARM64, WoW64/Hangover) - Mesa 24.x Panfrost driver (Mali-G52 MP2, RK3566 SoC) - MESA_GL_VERSION_OVERRIDE=3.1COMPAT - UseGLSL=enabled, CSMT=1 - Game: FlatOut (2004, GOG), Direct3D 9 fixed-function + shader ### Expected behavior Pixels with alpha < reference value should be discarded (not drawn), producing cutout shapes for vegetation, fences, etc. ### Actual behavior All pixels render regardless of alpha value. The full billboard quad is visible as a solid black rectangle. The texture data IS loaded correctly (color channels render fine), only the alpha test/discard is missing. ### Root cause analysis Panfrost is a GLES-derived GL driver. It advertises GL 3.1 COMPAT but does NOT implement the fixed-function GL_ALPHA_TEST pipeline in hardware. The glEnable(GL_ALPHA_TEST) + glAlphaFunc() calls silently do nothing. wined3d's GLSL backend has code to emit "discard" in fragment shaders for alpha test, but in compat profile contexts it appears to rely on the driver's fixed-function GL_ALPHA_TEST instead of always using shader-based discard. On desktop GPUs (NVIDIA, AMD, Intel) this works because they implement GL_ALPHA_TEST in hardware. On GLES-derived drivers (Panfrost, Lima, freedreno, v3d, Zink-on-GLES) it silently fails. ### Workaround Embedding explicit ps_2_0 pixel shaders with texkill instructions in the game's .sha effect files forces Wine to compile the discard into the GLSL fragment shader at shader creation time, bypassing the runtime render state path. This confirms the GLSL discard mechanism itself works — the issue is that wined3d doesn't activate it for compat profile contexts. ### Proposed fix wined3d should always use shader-based alpha test (uniform-gated discard) regardless of GL profile, or probe whether GL_ALPHA_TEST actually functions at init time. This would fix alpha test for all GLES-derived Mesa drivers on ARM (Panfrost, Lima, freedreno, v3d) and potentially Zink. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59601] New: dlls\kernelbase\debug.c isn't shipping with the debug symbols

You can instead see in bug 46010 that when somebody is building wine on their own system, the debugger can find it. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59607] New: ACD/ChemSketch 2025.2.1: crashes immediately when copying structures to clipboard (Ctrl+C)
by WineHQ Bugzilla April 1, 2026

April 1, 2026

http://bugs.winehq.org/show_bug.cgi?id=59607 Bug ID: 59607 Summary: ACD/ChemSketch 2025.2.1: crashes immediately when copying structures to clipboard (Ctrl+C) Product: Wine Version: 11.0 Hardware: x86-64 OS: MacOS Status: UNCONFIRMED Severity: normal Priority: P2 Component: ole32 Assignee: wine-bugs(a)list.winehq.org Reporter: massyfederici(a)gmail.com Created attachment 80672 --> http://bugs.winehq.org/attachment.cgi?id=80672 Logs of bugs ### Environment - OS: macOS (MacBook Air) - Wine version: 11.0 (Stable/Dev) - Software: ACD/ChemSketch (Freeware) 2025.2.1 - Build: 147869 (26 Jan 2026) - File Version: C65E41 ### Problem Description The application ACD/ChemSketch 2025.2.1 crashes instantly when attempting to copy any drawn object or chemical structure to the clipboard using Ctrl+C or the "Edit -> Copy" menu. ### Steps to Reproduce 1. Start ACD/ChemSketch 2025.2.1 in a clean WINEPREFIX. 2. Draw a simple structure (e.g., a benzene ring or a single bond). 3. Select the structure using the selection tool. 4. Press Ctrl+C to copy. ### Actual Result The application terminates abruptly with a crash as soon as the clipboard action is triggered. ### Expected Result The structure should be copied to the clipboard for internal use or for pasting into other applications (via Wine's clipboard synchronization). ### Additional Notes The issue persists on a clean Wine 11.0 installation without any DLL overrides. This version of ChemSketch is very recent (Jan 2026). The terminal output shows multiple EMF_Update_MF_Xform World transform failed! errors, followed by fixme:ole:OleQueryLinkFromData ...,stub!. It appears the crash is triggered when the application attempts to populate the clipboard with OLE data and Enhanced Metafiles (EMF). I am attaching the full terminal log and backtrace as a .txt file. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59603] New: MapViewOfFile3 with MEM_REPLACE_PLACEHOLDER uses Committed_AS which it shouldn't

http://bugs.winehq.org/show_bug.cgi?id=59603 Bug ID: 59603 Summary: MapViewOfFile3 with MEM_REPLACE_PLACEHOLDER uses Committed_AS which it shouldn't Product: Wine Version: 11.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)list.winehq.org Reporter: hkarlsson(a)gmail.com Distribution: --- MapViewOfFile3 with MEM_REPLACE_PLACEHOLDER is a reservation on windows and does not go towards committed memory. On wine (without vm.overcommit_memory=1) it fails if you try to do this on a range that is larger than what is available in commit space. So solution should be somewhere to use mmap MAP_NORESERVE for the MEM_REPLACE_PLACEHOLDER placeholder path.
