[Bug 52254] New: Cold Steel Subs: Application is not transparent (relies on DwmExtendFrameIntoClientArea)
by WineHQ Bugzilla Oct. 10, 2026

Oct. 10, 2026

https://bugs.winehq.org/show_bug.cgi?id=52254 Bug ID: 52254 Summary: Cold Steel Subs: Application is not transparent (relies on DwmExtendFrameIntoClientArea) Product: Wine Version: 7.0-rc2 Hardware: x86-64 URL: https://zerofield.net/2020/09/30/hajimari-no-kiseki-sp readsheet-translation/ OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: dwmapi Assignee: wine-bugs(a)winehq.org Reporter: johnny(a)localmomentum.net Distribution: --- Created attachment 71376 --> https://bugs.winehq.org/attachment.cgi?id=71376 ColdSteelSubs transparency code (currently not in the distributed application) This application provides a transparent clickthrough overlay to show English translations on top of the original Japanese source. It relies on layered windows and DwmExtendFrameIntoClientArea to handle the transparent display. Currently, the main UI elements show, but the game (or any other application) does not show through. This seems to be because DwmExtendFrameIntoClientArea is only a stub. I'm not sure if that's the only reason it's not transparent, but it's at least one of the reasons. The program itself uses the unity3d engine along with some native dll calls to the relevant user32 apis to handle the transparency. I was able to get a copy of the relevant code (but not the whole application), of which I will attach. Since I can't get all of the code, I've been using an unity sample application to try to figure out some parts myself (the relevant code is here https://github.com/pheonise/Unity3D-Desktop-Overlay/blob/master/Assets/Scri…) This unity3d application works as expected on windows, but is not transparent via wine (as expected). When i comment the call to DwmExtendFrameIntoClientArea, then it its also no longer transparent on windows as well. It seems that if the sample application works, then I can make sure the dev applies to the same technique to the overlay application. Please let me know If i can provide any more information. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58921] New: WebView2 does not work with Windows version setting 8.1 or newer
by WineHQ Bugzilla Oct. 10, 2026

Oct. 10, 2026

http://bugs.winehq.org/show_bug.cgi?id=58921 Bug ID: 58921 Summary: WebView2 does not work with Windows version setting 8.1 or newer Product: Wine Version: 10.18 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: felixhaedicke(a)web.de Distribution: --- Created attachment 79605 --> http://bugs.winehq.org/attachment.cgi?id=79605 webview.log (log created by WebView2) For testing WebView2, I am using my "SimpleWebView2Browser", see https://github.com/felixhaedicke/SimpleWebView2Browser for source code and binaries. Steps to get it running on a fresh wineprefix: * Install WebView2 runtime using the "Evergreen Standalone Installer" for x64 from Inst https://developer.microsoft.com/en-us/microsoft-edge/webview2 * Set Windows version to Windows 7 or 8. * Use my "SimpleWebView2Browser" binaries from https://github.com/felixhaedicke/SimpleWebView2Browser/releases/tag/v0.1 It is sufficient to set the Windows version for "msedgewebview2.exe" (which is part of the WebView2 runtime): wine reg add "HKEY_CURRENT_USER\Software\Wine\AppDefaults\msedgewebview2.exe" /v Version /t REG_SZ /d win8 It does not work with Windows version set to 8.1, 10 or 11. The problem is probably that WebView2 tries to use the DirectComposition API on Windows 8.1 or newer. Message in the WebView2 debug log: DCompositionCreateDevice failed: Not implemented. (0x80004001) The attached WebView2 debug log was captured using the WebView2 logging functions, which can be enabled using the WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS environment variable. Command line used to start the browser process, and to capture the attached logs: WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS="--enable-logging --v=1 --log-file=c:/webview.log" wine SimpleWebView2Browser.exe 2> wine-output.txt -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 44743] New: Segfault in Wine-d3d. Affected; Anno1404, LAA flag set

https://bugs.winehq.org/show_bug.cgi?id=44743 Bug ID: 44743 Summary: Segfault in Wine-d3d. Affected; Anno1404, LAA flag set Product: Wine Version: 3.2 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d Assignee: wine-bugs(a)winehq.org Reporter: aphid.mmonly(a)gmail.com Distribution: --- Created attachment 60753 --> https://bugs.winehq.org/attachment.cgi?id=60753 Stack backtrace and loaded libraries To reproduce the specific segfault: 1) Install Anno1404, either the steam version or the GoG one. 2) Patch the I.A.A.M. mod over Anno 1404 3) Apply the '4gb patch' to the result (or flag the executable as large-address-aware). 4) Launch the game, play a big map for about 60-70 minutes (or leave it running for that long). Wined3d will segfault at address (+0x34dee) (0x0033f038), according to winedbg. See the attached file for more information. As far as I've tested, it's always that exact spot where the fault happens. Without a debugger attached, a user would experience a freezing program. If ran in full-screen mode, it will also lock up your X session, requiring the user to terminate the wine application from another tty console. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 48406] New: Epic Games Store fails to install prerequisites with Wine Mono

https://bugs.winehq.org/show_bug.cgi?id=48406 Bug ID: 48406 Summary: Epic Games Store fails to install prerequisites with Wine Mono Product: Wine Version: 5.0-rc3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: sashok.olen(a)gmail.com Distribution: --- Created attachment 66178 --> https://bugs.winehq.org/attachment.cgi?id=66178 log To reproduce the issue, you just need to install Epic Games Store with Wine Staging. After you launch it and it downloads its own files, it will try to install its "prerequisites", which will fail with Wine Mono. The issue disappears if you install "dotnet48" using winetricks, or if you launch EGS with -SkipBuildPatchPrereq flag, but neither are really good solutions as some games don't seem to work with dotnet48 and -SkipBuildPatchPrereq sometimes doesn't work. Should be noted that on real Windows, it seems to install dotnet48 using "Windows Features" component. Attaching standard debug output. Let me know if you need a log with additional debug channels. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
