[Bug 59522] New: explorerframe: ITaskbarList3 SetProgressValue/SetProgressState stubs - could use native desktop backends
by WineHQ Bugzilla May 29, 2026

May 29, 2026

http://bugs.winehq.org/show_bug.cgi?id=59522 Bug ID: 59522 Summary: explorerframe: ITaskbarList3 SetProgressValue/SetProgressState stubs - could use native desktop backends Product: Wine Version: 11.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: explorerframe Assignee: wine-bugs(a)list.winehq.org Reporter: Robert-Gerigk(a)online.de Distribution: --- ITaskbarList3::SetProgressValue() and SetProgressState() in dlls/explorerframe/taskbarlist.c are currently stubs (FIXME + return S_OK). This causes Issues with .NET/WPF applications that use the Windows 7+ taskbar progress API. Some appplications (e.g. WPF apps using TaskbarItemInfo) deadlock or behave incorrectly when the COM call chain around these methods interacts with the UI thread. Wine already implements plattform-specific desktop integration in several places: - macOS: Full Cocoa integration (NSStatusBar, NSDockTile) in winemac.drv - X11: EWMH hints including _NET_WM_STATE_DEMANDS_ATTENTION in winex11.drv - Wayland: xdg-toplevel-icon-v1 protocol in winewayland.drv - DBus: Production clients for BlueZ and UDisks in winebth.sys and mountmgr.sys A natural Extension would be implementing taskbar progress via the com.canonical.Unity.LauncherEntry DBus interface, wich is supported by KDE Plasma, GNOME, and other Linux desktop environments. Firefox and LibreOffice already use this interface for native taskbar progress. Proposed mapping: TBPF_NOPROGRESS -> progress-visible: false TBPF_NORMAL -> progress-visible: true, progress: value TBPF_INDETERMINATE -> progress-visible: true, progress: 0.0 TBPF_ERROR -> urgent: true TBPF_PAUSED -> progress-visible: true (no direct equivalent) The implementation would follow the existing DBus pattern from mountmgr.sys/dbus.c (dlopen/dlsym, graceful degradation when libdbus-1 is unavailable). I'd be willing to work on a Linux/DBus patch if there's interest. Looking for feedback on: 1. Is this the right component (explorerframe) or should this be handled in the platform drivers (winex11.drv, winewayland.drv)? 2. How should the .desktop file association be resolved? (DBus needs an application:// URI) 3. Any concerns about adding a libdbus-1 dependency to explorerframe? I'm currently working on getting KNX ETS 6.4 (a .NET/WPF application) running under Wine and ran into several issues along teh way, this being one of them. The application uses TaskbarItemInfo for progress display wich leads to Problems in the COM/UI thread interaction. ETS 6.4 does run on Linux now, but only trough launch scripts, .dll patches, registry workarounds, and a heavily patched Wine prefix (winetricks dotnet48 + manual fixes) - it would be great to reduce those workarounds over time. I am mostly a solo devloper with an electrical engineering background and fairly new to collaborative development on Gitlab/GitHub, so I'd appreciate any Guidance on the right approach for this - happy to learn. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 57329] New: Desktop files generated by Wine do not conform to the Desktop Entry Specification
by WineHQ Bugzilla May 29, 2026

May 29, 2026

https://bugs.winehq.org/show_bug.cgi?id=57329 Bug ID: 57329 Summary: Desktop files generated by Wine do not conform to the Desktop Entry Specification Product: Wine Version: 9.20 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: meator.dev(a)gmail.com Distribution: --- Desktop files generated by Wine do not conform to the latest (and older) version to of the Desktop Entry Specification, primarily the Exec key specification: https://specifications.freedesktop.org/desktop-entry-spec/1.5/exec-variable… For example, this is how the desktop file for Notepad++ looks like (located at /home/meator/.local/share/applications/wine/Programs/Notepad++.desktop): [Desktop Entry] Name=Notepad++ Exec=env WINEPREFIX="/home/meator/.wine" wine C:\\\\ProgramData\\\\Microsoft\\\\Windows\\\\Start\\ Menu\\\\Programs\\\\Notepad++.lnk Type=Application StartupNotify=true Path=/home/meator/.wine/dosdevices/c:/Program Files/Notepad++ Icon=7ABC_notepad++.0 StartupWMClass=notepad++.exe I will ignore the `env WINEPREFIX="/home/meator/.wine"` part of Exec now. The Exec key parsing is done in two rounds (that's why there are so many backslashes). The first round is common to all keys of type string, localestring and iconstring (which includes the Exec key). The standard mandates: > The escape sequences \s, \n, \t, \r, and \\ are supported for values of type string, localestring and iconstring, meaning ASCII space, newline, tab, carriage return, and backslash, respectively. This is how the command line looks after undoing the first layer of escapes: > wine C:\\users\\meator\\AppData\\Roaming\\Microsoft\\Windows\\Start\ Menu\\Programs\\Microsoft\ Office\ PowerPoint\ Viewer\ 2003.lnk Then the Exec quoting continues. The standard mandates: > Quoting must be done by enclosing the argument between double quotes and escaping the double quote character, backtick character ("`"), dollar sign ("$") and backslash character ("\") by preceding it with an additional backslash character. Implementations must undo quoting before expanding field codes and before passing the argument to the executable program. Reserved characters are space (" "), tab, newline, double quote, single quote ("'"), backslash character ("\"), greater-than sign (">"), less-than sign ("<"), tilde ("~"), vertical bar ("|"), ampersand ("&"), semicolon (";"), dollar sign ("$"), asterisk ("*"), question mark ("?"), hash mark ("#"), parenthesis ("(") and (")") and backtick character ("`"). The first problem is that the second argument is not enclosed in double quotes, so all escapes in it are unspecified. The second problem is that `\ ` space escape is used, which is not specified (this is the most severe problem). It is specified as a "reserved character", but not as a character requiring a backslash escape. Because of these issues, fully conformant desktop file parsers will fail to parse desktop files generated by Wine. This is how a fixed Notepad++ desktop file looks like: [Desktop Entry] Name=Notepad++ Exec=env "WINEPREFIX=/home/meator/.wine" wine "C:\\\\ProgramData\\\\Microsoft\\\\Windows\\\\Start Menu\\\\Programs\\\\Notepad++.lnk" Type=Application StartupNotify=true Path=/home/meator/.wine/dosdevices/c:/Program Files/Notepad++ Icon=7ABC_notepad++.0 StartupWMClass=notepad++.exe I have also quoted `WINEPREFIX=/home/meator/.wine` in whole, because the entire argument should be quoted according to the standard (but I consider this issue to be less important).

Attached is the terminal window log showing all the fixme errors from Wine. The current working directory was my personal directory under drive_c/users, which is where I copied the Family Tree Maker install program FTM2017.EXE. The large gaps of blank lines in the log were me adding carriage returns in the terminal to separate different windows in the InstallShield wizard. The last clump appeared while the InstallShield file copy progress window was showing, followed by the installation failure window. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59555] New: Star Wars: Knights of the Old Republic - Rendering failure with active framebuffer effects
by WineHQ Bugzilla May 29, 2026

http://bugs.winehq.org/show_bug.cgi?id=59555 Bug ID: 59555 Summary: Star Wars: Knights of the Old Republic - Rendering failure with active framebuffer effects 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: accounts.winehq(a)vv221.fr Distribution: --- Up to WINE 10.0, framebuffer effects could be enabled in Star Wars: Knights of the Old Republic with no adverse effect on rendering. With WINE 11.5 it leads to a failure to render the game world (including any geometry, models, etc.). Text dialogues and other 2D interface pieces can be seen, with some heavy flickering effect. When trying to take a screenshot I only get a solid black image, even when text dialogue could be seen on the actual game screen. The actual gameplay seems to work fine, this is almost certainly only a rendering error. I have not tested other WINE builds yet, but I am going to do that to get a better idea of where the regression is hiding. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59732] New: Custom WinXP/7 app printing garbled from wine 9 onwards

For all this time, I've mostly managed to make it work on Debian/Devuan Linux and Wine. Nowadays, we're using mostly Devuan Daedalus / Debian Bookworm and Wine 8, the app works perfectly. Then I've started testing Devuan Excalibur / Debian Trixie which comes with Wine 10, and I've learned it had ODBC broken which in turn broke my app. No matter, I installed wine-stable 9 from winehq, and it worked just fine. Or so I thought... Someone else which was testing the app on wine 9 let me know about several "documents" which the app prints to PDF or physical printers, which on wine 8 comes out perfectly, but on wine 9 and onwards come out garbled. You can see here on https://shorturl.at/RJ107 an example of a document printed all right, and the same document printed garbled at https://shorturl.at/q5Rjw Up to now I've had the same results with wine-stable 11 and wine-staging up to 11.8. What I'd like to know if there's some way to debug the printing, perhaps with WINEDEBUG?
