http://bugs.winehq.org/show_bug.cgi?id=59745 Bug ID: 59745 Summary: Wine crashes when a custom window is created to show information Product: Wine Version: 11.8 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: matthias0178+wine(a)gmail.com Distribution: --- Created attachment 80922 --> http://bugs.winehq.org/attachment.cgi?id=80922 Source code of the test program I created a program using C and the Windows API. This program was designed to create and display a specific window containing help text rendered via GDI. As soon as the user pressed any key on the keyboard or clicked with the mouse, the special window was supposed to be destroyed and the application terminated. Since this program functioned flawlessly on Windows but crashed under Wine immediately after displaying and destroying the special window, I developed a small test program that demonstrates the bug. This test program logs to the command line what occurs when the same task is executed in a simplified manner. I have attached the source code for this tiny test program. You may copy, modify and distribute it without restrictions to the extent permitted by law. On the Debian 13 console, the console output is not the same as in the console of Windows 11. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=53812 Bug ID: 53812 Summary: Text does not show in Some APPs with native wine7.19 Product: Wine Version: 7.19 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: blocker Priority: P2 Component: gdi32 Assignee: wine-bugs(a)winehq.org Reporter: 399989567(a)qq.com Distribution: --- Created attachment 73324 --> https://bugs.winehq.org/attachment.cgi?id=73324 how to reproduce problem I filed a bug(# Bug 53739) with the font display issue before, because I was doing some font replacements (seems to involve dwrite).This problem appears to be the same as the previous one, but it's not the same problem. This problem occurs in different sections of QQ, DingTalk, and corporate WeChat. For example, some fonts on the landing page of QQ are not displayed； some fonts are not displaye when sending a message on the meeting interface of corporate WeChat. Among them, the problem of QQ is the easiest to reproduce(even if you don't have an account, you can reproduce it), so I will use QQ to explain the problem below. 「Problem Description In general」—— use native unmodified wine In general, the font of QQ can be displayed normally on my virtual machine, but it cannot be displayed normally on my physical machine，with the same Language Environment and System installation scene > $ echo LANG = zh_CN.UTF-8 > System installation scene：debian-live-11.4.0-amd64-kde.iso > System installation scene download URL:https://drive.google.com/file/d/14FJVpGkLNTJrDlU9SQW38eSIFlr_qjUB/view?… 「The machine I use」 M1: "physical machine" debian-11.4.0-KDE M2: "virtual machine" debian-11.4.0-KDE 「 Problem Description 」 I just downloaded the source code of wine 7.19 and make it. I click to add an account, the font display of QQ fails on M1, but successed on M2. By use WINEDEBUG=+relay,I find when text show on M2, APPs called API:ScriptTextOut,and then text show successed. But on M1, APPs called API:ExtTextOutW, and then text show fails. I just started to suspect that QQ has different versions installed on different machines, so I packaged all the files of QQ installed on the virtual machine into a zip file, and then took this file to the physical machine to run, but the text still cannot be show on the physical machine. I don't know why QQ calls different APIs on the physical machine and the virtual machine to output text, so I'm asking for your help. What channel should I use to check my environment？nls?locale? 「Reproduce Problem」 The picture(how_to_..._proble,.png) shows the operation process QQ downloardURL:https://im.qq.com/download QQ Version:9.6.7 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59550] New: Implement AppDefaults registry toggle for wcmd to sanitize forward slashes in execution paths (Resolves Unreal Engine update scripts)
by WineHQ Bugzilla July 1, 2026

July 1, 2026

http://bugs.winehq.org/show_bug.cgi?id=59550 Bug ID: 59550 Summary: Implement AppDefaults registry toggle for wcmd to sanitize forward slashes in execution paths (Resolves Unreal Engine update scripts) Product: Wine Version: 11.5 Hardware: arm OS: MacOS Status: UNCONFIRMED Severity: normal Priority: P2 Component: cmd Assignee: wine-bugs(a)list.winehq.org Reporter: smcclenahan(a)gmail.com Created attachment 80605 --> http://bugs.winehq.org/attachment.cgi?id=80605 wcmdmain.c Registry Hook for CmdForgiveSlashes Currently, wcmd strictly parses forward slashes (/) as command switches. When modern cross-platform engines (specifically Unreal Engine 4/5, e.g., Borderlands 4) attempt to launch background update scripts via cmd.exe /c, they frequently pass un-sanitized, mixed-slash paths (e.g., C:/users/.../PersistentDownloadDir/GbxRelaunch.bat). Because wcmd evaluates the slash as an invalid switch (e.g., /users), the execution fails instantly with an unrecognized command error. This breaks automatic game restarts and hotfix pipelines for numerous titles. (See attached terminal_output.txt for the exact error). Proposed Solution: Introduce an opt-in registry toggle within the AppDefaults hive that allows wcmd to sanitize forward slashes to backslashes for specific calling executables before parsing. * Registry Key: HKCU\Software\Wine\AppDefaults\[CallingProcess.exe] * Proposed Value: "CmdForgiveSlashes"="1" (String or DWORD) * Behavior: When wcmd is spawned, it checks the AppDefaults of the parent process. If the flag is present, a lightweight sanitization routine converts / to \ in the execution buffer before the standard wcmd parsing logic takes over. Architectural Rationale & Preempting Regressions: * Zero Regression Blast Radius: By defaulting to strict legacy parsing and requiring an explicit AppDefaults override, there is zero risk to legacy enterprise scripts, background redistributables, or unrelated software within the same WINEPREFIX. The execution state remains entirely deterministic. * Avoiding Hardcoded Hacks: This prevents the need to continuously merge game-specific string exceptions into the core wcmdmain.c codebase as new games release. * Empowering Downstream Wrappers: Native Windows cmd.exe occasionally relies on undocumented, dynamic heuristics to successfully execute these mixed-slash paths. Perfectly cloning those undocumented heuristics in wcmd is dangerous for legacy stability. Exposing this registry hook gives downstream maintainers (like Proton and CrossOver) a safe, standardized way to configure the environment via their own application profiles without patching Wine's core C code.

[Bug 36439] New: Wildstar IE7 error on launch ( IE fixmes )

http://bugs.winehq.org/show_bug.cgi?id=36439 Bug ID: 36439 Summary: Wildstar IE7 error on launch ( IE fixmes ) Product: Wine Version: 1.7.18 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: funkydude87(a)hotmail.co.uk Created attachment 48461 --> http://bugs.winehq.org/attachment.cgi?id=48461 fixmes When launching the Wildstar executable an error pops up saying "You do not have a browser supported by the Wildstar launcher. Internet Explorer 7 or later is required. Continue?" If I continue, a wine error (page fault) is produced. Something is preventing the launcher from detecting that IE is "installed". Attached is the console paste of all the "fixmes" produced when I click continue, before the page fault popup is shown. I could post the page fault but I don't think there's any point? I think it's the amount of IE-related fixmes that causes the fault. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 38468] New: Allow navigating to folders with colon in their name
by wine-bugs＠winehq.org June 30, 2026

June 30, 2026

https://bugs.winehq.org/show_bug.cgi?id=38468 Bug ID: 38468 Summary: Allow navigating to folders with colon in their name Product: Wine Version: 1.7.38 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: yajo(a)openaliasbox.org Distribution: --- Right now, the current implementation of GVFS mounts samba folders in paths like: /run/user/<UID>/smb-share:server=hostname,share=sharename/ Some Windows apps don't work fine with those characters in the path. For example, if I want to install something I have in that share and I run the `setup.exe` file from `wine explorer`, it works; but if I run it from `wine uninstaller`, it fails saying that characters "/:<>|" are forbidden in paths. Also, if I installed MS Excel and try to open a .xslx file from a samba share in Nautilus (right button > open with > MS Excel), it fails saying that it cannot find the file. This makes the UX very uncomfortable, because the user needs to copy the file to a local drive, edit it, and then copy it back to the network share. Independently if Bug 34748 gets fixed or not, IMHO wine itself should do something with Linux paths containing those characters, the same way it does when transforming "/" to "\" or when dealing with uppercase/lowercase files. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=40736 Bug ID: 40736 Summary: In notepad Ctrl+[Grey /] cause '/' char to be added Product: Wine Version: 1.9.11 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: gur.stavi(a)gmail.com Distribution: --- The issue is about pressing the combination of CTRL + sys keys from the right side numeric keypad of the keyboard: CTRL-[/] CTRL-[*] CTRL-[-] CTRL-[+] It can be reproduced in Notepad. In Notepad under Windows these sequences will do nothing. In Notepad under Wine these sequences will cause the character to be added to the document. Perhaps it is related to 'TranslateAccelerator' API but this is just a guess. The real problem is with 'Notepad++' where these sequences are the default accelerators for zoom control so chars are added to the document whenever zoom is changed.
