How can I debug an issue where a specific commit breaks transparency?
by zhengxianwei 16 Aug '25

16 Aug '25

>> | * cb787d0c566 - (2 months ago) win32u: Use a pbuffer to implement GL on memory DCs. - Rémi Bernon This commit caused one of my images to go from transparent to non-transparent. How should I debug this? I tried using RenderDoc to capture, but it errors out saying that on Linux it supports the core profile and not the compatibility profile. When I capture a trace with apitrace, it seems the program isn’t using a standard OpenGL frame rendering flow. May I ask what the default method is in Wine for debugging OpenGL or investigating incorrect/garbled rendering?

Folks, Just a heads up that I'm going to be traveling for the next 3 weeks. I'm still going to review and commit MRs, but on a somewhat irregular schedule. Also there won't be a new release during that time, so Wine 10.13 will be out on August 15. -- Alexandre Julliard julliard(a)winehq.org

Upcoming vkd3d 1.17 release
by Henri Verbeet 17 Jul '25

17 Jul '25

Hi all, The planned release date for vkd3d 1.17 is Thursday August 21. That means the public API will become frozen a week from now on July 24, and features will be frozen two weeks before the release, on August 7. This does not mean that development should slow down or stop, of course; after making sure that we're in good shape to release, this would be the ideal time to make sure any larger features are ready to get merged at the start of the next development cycle. As usual, if you're an upstream vkd3d developer, please do the following: - Keep an eye on Bugzilla for any reported regressions. - Review any API changes since the previous release. - Verify that all vkd3d tests pass on your hardware/setup, and please send fixes if they don't. - Review and improve the documentation. - Get any larger features ready to get merged at the start of the next development cycle. If you're a downstream user of vkd3d, please test your applications for any regressions, and file bug reports if you find any. The planned release date for vkd3d 1.18 is November 20. A tentative release schedule for future releases can be found on the vkd3d wiki[1]. Regards, Henri [1] https://gitlab.winehq.org/wine/vkd3d/-/wikis/release-schedule

How to use AddressSanitizer with Wine?
by Alex Henrie 13 Jul '25

13 Jul '25

Dear oenologists, I would like to use GCC's AddressSanitizer [1] to investigate a memory corruption bug in Wine. There must be a way to do it because I see multiple references to "ASan" in the Wine commit log in commits from this year.[2] I found some instructions on the WineHQ wiki,[3] but I get a myriad of linker errors when I try to follow them. What Linux distributions can successfully compile Wine with libasan? Are there special steps not mentioned in the wiki? Does AddressSanitizer work with MinGW, or only with non-PE builds? I'd love to get AddressSanitizer working myself, but even if I can't, thanks to Bernhard and Nikolay for using it to fix a lot of bugs already. -Alex [1] https://github.com/google/sanitizers/wiki/AddressSanitizer [2] https://gitlab.winehq.org/wine/wine/-/commits/master?search=ASan [3] https://gitlab.winehq.org/wine/wine/-/wikis/Building-Wine#memory--address-c…

Add option to winebuild to disable ASLR/dynamicbase
by Tres Finocchiaro 09 Jul '25

09 Jul '25

Hi, I'm a maintainer of LMMS and we use a wine bridge for loading 32-bit and 64-bit VST plugins into the Linux version of our software. We've recently updated our build tools and noticed that some of our older 64-bit VSTs fail to load. After a lot of back and forth, we've isolated the issue to the following wine commit: > Commit 518e394 julliard committed on Sep 25, 2023 > winebuild: Set ASLR-related dll flags by default. > https://github.com/wine-mirror/wine/commit/518e394794160818ffe6826c874ff2f5… One of our developers has proposed a patch which reverts this behavior here: https://github.com/Fastigium/winebuild/commit/7f9e27e44cfb8eba79f3850f46e12… My questions are as follows: 1. Would winehq be receptive to a winebuild flag that allows the old behavior? 2. If acceptable, would you prefer LMMS author this patch, or is this change trivial enough/small enough that the winehq team would prefer to tackle it themselves? 3. Lastly, quoting a past mailing list convo, should we be doing our wine bridge differently? Currently we build RemovePluginVst64.so.exe. "[...] I don't think we have any plans to deliberately break the old all-in-one .dll.so binaries. It is quite likely that this functionality will bitrot over time though. Also the functionality that the PE/unix split was introduced for won't be available that way [...]" Source: https://list.winehq.org/mailman3/hyperkitty/list/wine-devel@winehq.org/mess… Thanks kindly for your time, -Tres - Tres.Finocchiaro(a)gmail.com

wine and safearray marshalling
by Ilya Sokolov 30 Jun '25

30 Jun '25

Hello I have a question about how WINE processes marshalling between .Net Core code and COM object. There is an application, which runs in x64 prefix. Application contains COM object and .Net Core user interface. Data between the com object and the UI are transmitted in structures, which contains safearrays of other structures, some of structures include BSTRs. Some example of code is listed below: typedef [uuid(59d7e939-2a40-4d4c-a750-e8bd85f08a77)] > struct stLimitsSettings > { > float AbortMinus; > float AbortPlus; > float MaxDriveVoltage; > float MaxShakerAcc; > float MaxShakerDisp; > float MaxShakerVel; > float MaxVDivGForRunning; > float MaxVDivGForStartup; > int PhusicalUnitIndex; > float ProductMass; > BSTR ShakerProducerName; > enLimitAndLevelUnitType TolAndAbortUnits; > float TolMinus; > float TolPlus; > int UnexceedLimitsNum; > float UnExceedAverAlpha; > float UnExceedStableLinePrec; > BSTR ShakerModelName; > BOOL CheckShakerLimits; > float SpectOutOfLimitsPers; > BOOL UseSigmaClippingInCheck; > enShkLimitType ShkLimitType; > > BOOL useMultyShkUnExFullLimits; > > stDetailedMassDesc DetailedMass; > BOOL LimitRandomLinesOutsideTheProfile; > > > float > LinesOutsideTheBorder; > > > BOOL > UseTableLimits; > > enWhatToLiminInRndSpectrum WhatToLimitInSpectrum; > float AbDDBSpectrumPlus; > float AbDDBSpectrumMinus; > float TolDDBSpectrumPlus; > float TolDDBSpectrumMinus; > enLimitAndLevelUnitType SpectrumLimitUnitType; > BOOL DisableLowLimitWhileOnNotching; > SAFEARRAY(stShkLimitPair) LimitsTable > SAFEARRAY(stChUnexceedLimit) UnexceedChParameters; > > BOOL CheckChannelsOnOverload; > }stLimitsSettings; > > > typedef [uuid(311D09EA-7943-4A18-ADAB-CFE991E4A3D1), > struct stSyntheseSRSPoint > { > float Freq; > float Responce; > float NegativeMax; > float PositiveMax; > } stSyntheseSRSPoint; > cpp_quote("struct > __declspec(uuid(\"{311D09EA-7943-4A18-ADAB-CFE991E4A3D1}\")) > stSyntheseSRSPoint;") > > typedef [uuid(6A8B679F-E7C6-45F6-A0DB-378D2E4CD0ED), > struct stSRSPointsFromSynthese > { > int PointsCount; > SAFEARRAY(stSyntheseSRSPoint) SRSPoints; > }stSRSPointsFromSynthese; > > typedef [uuid(747684a8-7b15-4215-8484-7e674fce3e16), > struct stSRSProfilesDescription > { > int ID; > BSTR Name; > float EndAcc; > float EndVel; > float EndDisp; > float MaxAcc; > float MaxVel; > float MaxDisp; > float PWA; > DWORD CompencateSeed; > stSRSSyntheseSettings SyntheseSettings; > stSRSTable SRSTable; > stWaveletsTable Wavelets; > stSRSPointsFromSynthese SynthesePoints; > DWORD RealShkLenInSamples; > float RealSampleRate; > }stSRSProfilesDescription; > cpp_quote("struct > __declspec(uuid(\"{747684a8-7b15-4215-8484-7e674fce3e16}\")) > stSRSProfilesDescription;") > > > typedef [uuid(d4b7ee82-d6ca-4131-9ab2-1c0ca9093935), > struct stMosaSRSProfiles > { > int ProfilesCount; > float MaxAcc; > float MaxVel; > float MaxDisp; > float EndAcc; > float EndVel; > float EndDisp; > float ShkTimeInSec; > double Te; > double TeConc; > SAFEARRAY(stSRSProfilesDescription) Profiles; > }stMosaSRSProfiles; > > typedef [uuid(ee6226d6-3ac9-47b4-aab3-3e1d612b8c69), > struct stMosaSRSTestSettingsStruct > { > BOOL IsReportSettingsInited; > BOOL TestStartQuestState; > DWORD TestTimeInSec; > DWORD TotalShkCount; > int ActiveOutputsCount; > int AxisesCount; > SAFEARRAY(stMultishakerOutputLimitsDescription) OutputLimits; > stMosaSRSProfiles TestProfiles; > stMultishTaskToAxisMap Axises; > stMultishakerReportSettings ReportSettings; > stAnalyseSettings AnalysesSettings; > stChannelsConfigSettings ChannelsConfig; > stControlSettings ControlSettings; > stLimitsSettings Limits; > stSchedule Schedule; > stDataSaveSettings DataSaveSettings; > }stMosaSRSTestSettingsStruct; > > Sometimes getting data woks well, however sometimes an error appears with log which looks like: 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:ole:IRecordInfoImpl_RecordClear Not supported vt = 29 > 06e8:fixme:advapi:RegisterEventSourceW ((null),L".NET Runtime"): stub > 06e8:fixme:advapi:ReportEventW > (00000000CAFE4242,0x0001,0x0000,0x00000402,0000000000000000,0x0001,0x00000000,00007FFFFE27A7F0,0000000000000000): > stub > 06e8:err:eventlog:ReportEventW L"Application: VisProbe_SL.exe\n" > 06e8:err:eventlog:ReportEventW L"CoreCLR Version: 8.0.1425.11118\n" > 06e8:err:eventlog:ReportEventW L".NET Version: 8.0.14\n" > 06e8:err:eventlog:ReportEventW L"Description: The process was terminated > due to an unhandled exception.\n" > 06e8:err:eventlog:ReportEventW L"Exception Info: > System.AccessViolationException: Attempted to read or write protected > memory.

DXVK + DComp causes graphics rendering to fail
by zhengxianwei 29 Jun '25

29 Jun '25

I'm not sure whether this issue should be posted on the DXVK forum or here. If I've posted it in the wrong place, I apologize. I wrote a test program called dcomp_test.exe, which is already working under Wine. Its main function is to render circles, and the effect looks like this: [image: image.png] The actual operation is...： surface content = gdi * backgroup_alpha + swapchain[0] * foreground_alpha However, after replacing Wine's built-in DLLs with the ones I built from DXVK specifically dxgi, d3d8, d3d9, d3d10core, d3d11, and d3d12 I found that the circle was no longer rendered. The image extracted from the swapchain contained all zeros. [image: image.png] I did a quick trace and confirmed that it reached: 1. ID3D11DeviceContext1_DrawIndexed 2. ID3D11DeviceContext1_Draw https://github.com/wine-mirror/wine/blob/80bc1338bea7d9dac78ab449b4505e5bb9… So I feel that the circle is indeed being rendered onto the DXVK D3D11 swapchain, but I'm not sure at which step the content fails to be retrieved correctly. Any suggestions are welcome

How long after XFlush is called does the screen typically refresh correctly?
by zhengxianwei 29 Jun '25

29 Jun '25

I wrote a small test program that modifies a region using BitBlt, then checks the color of that region. I found that even immediately after BitBlt, it takes over 80 milliseconds before the correct color can be reliably detected. Then, I added an XSync(gdi_display, False) after the XFlush in x11drv_surface_flush, and the delay dropped to around 50–60 milliseconds. Is this expected? I was hoping that after BitBlt, the updated color could be detected immediately, without needing to add a delay or jitter. But it seems that XFlush only pushes the commands to the X server, and is not like vkQueuePresentKHR with semaphores or fences, which signal that the data has been pushed to the display (even though that still doesn’t guarantee vertical scanout completion).
