[Bug 45364] Frostpunk is very dark

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=45364 --- Comment #25 from Stian Low <wineryyyyy(a)gmail.com> --- wine-11.14-4dbf7bef7a0 now shows renderer=gl dark like vulkan whereas my previous tests/screenshots showed only vulkan dark. Despite gl now darker like vulkan for latest it seems more correct because MR-10567 fixes both renderers for the same reason so both should be bugged in the same way which is now the case which may have been originally before I started working this bug. MR-10567 seems practically complete and just awaiting final reviews and approvals. Winters finally almost over :) -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 60112] New: msvcrt: fopen incorrectly uses CreateFileW instead of CreateFileA

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=60112 Bug ID: 60112 Summary: msvcrt: fopen incorrectly uses CreateFileW instead of CreateFileA Product: Wine Version: 11.14 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: msvcrt Assignee: wine-bugs(a)list.winehq.org Reporter: brandowlucas(a)gmail.com Target Milestone: --- Distribution: --- Created attachment 81671 --> http://bugs.winehq.org/attachment.cgi?id=81671 Standalone MSVCRT narrow fopen reproducer This bug affects some FitGirl repack installers that rely on intercepting `CreateFileA` while reading their installation data. When a program calls `msvcrt.fopen()` with a narrow path, Wine converts the path to UTF-16 and opens it through `CreateFileW`. Windows MSVCRT keeps the narrow call on `CreateFileA`. Programs that replace the imported `CreateFileA` entry therefore work on Windows but fail on Wine. The standalone reproducer hooks the `CreateFileA` and `CreateFileW` imports in `msvcrt.dll`. Its `CreateFileA` hook maps the synthetic path `wine_fopen_virtual_input` to an anonymous pipe containing one byte. No third party DLL or application data is used. Unpatched Wine reports: fopen_route_summary | hookA=1 hookW=1 callsA=0 callsW=1 opened=0 read=0 byte=0 errno=2 win32Error=2 pass=0 Windows reports: fopen_route_summary | hookA=1 hookW=1 callsA=1 callsW=0 opened=1 read=1 byte=81 errno=0 win32Error=0 pass=1 Wine with the candidate patch reports: fopen_route_summary | hookA=1 hookW=1 callsA=1 callsW=0 opened=1 read=1 byte=81 errno=0 win32Error=0 pass=1 The focused unpatched trace shows the narrow `fopen()` call reaching the wide path and failing as a literal file lookup: trace:msvcrt:_wfsopen (L"wine_fopen_virtual_input",L"rb") trace:file:CreateFileW L"wine_fopen_virtual_input" GENERIC_READ FILE_SHARE_READ FILE_SHARE_WRITE creation 3 attributes 0x1 warn:file:CreateFileW Unable to create file L"wine_fopen_virtual_input" (status c0000034) The first incompatible behavior is in `dlls/msvcrt/file.c`: `_fsopen()` converts its narrow path with `wstrdupa_utf8()` and delegates to `_wfsopen()`, which reaches `_wsopen()` and `CreateFileW`. This bypasses the program supplied `CreateFileA` hook. The synthetic path is then treated as a literal file name, `fopen()` returns NULL, and the virtual input cannot be read. Reproduce: 1. Build `msvcrt_fopen_route_probe.c` as a 64-bit console executable with a MinGW compiler. 2. Run the executable on Windows and observe `callsA=1`, `callsW=0`, and `pass=1`. 3. Run the same executable with unpatched Wine and observe `callsA=0`, `callsW=1`, and `pass=0`. The candidate patch keeps narrow `_fsopen()` and `_sopen()` calls on `CreateFileA` while leaving the wide entry points on `CreateFileW`. It also adds an MSVCRT test that verifies which imported Win32 function receives a narrow `fopen()` call. Testing: - The standalone executable passes on Windows 10.0.19045.3324. - The standalone executable fails on Wine 11.14. - The standalone executable passes on Wine 11.14-14-g84fe968b936 with the candidate patch. - The 32-bit and 64-bit MSVCRT file test fails at the new assertions without the implementation change: `CreateFileA called 0 times` and `CreateFileW called 1 times`. - The 32-bit and 64-bit MSVCRT file test passes when the candidate patch is applied. I have attached a tar archive containing the reproducer source code and prebuilt binary, the native Windows result, Wine logs from before and after the fix, the focused debug trace, the candidate patch, and the build and run scripts. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59067] some Unreal Engine games don't render correctly with opengl renderer

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59067 --- Comment #4 from Stian Low <wineryyyyy(a)gmail.com> --- (In reply to Stian Low from comment #3) > renderer=gl darker than vulkan may be related/duplicate: > - https://bugs.winehq.org/show_bug.cgi?id=45364 If its the same bug as Frostpunk then it majorly affects nearly all Unity games I've tested when run via default win10 and worked around via `winecfg /v win8` which forces Unity not to use flip swap effects and swap backbuffers > 1. Frostpunk is not Unity so win8 does not workaround so MR-10567 is required. Curious if Unreal Engine behaves like Unity with win8 or earlier workaround or if it requires MR-10567 like Frostpunk. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 60023] IrfanView dialogs are rendered at a quarter of their actual size in Wine 11.13 under certain conditions, e.g. DPI = 144

Or when the spawned dialog has any close/minimize buttons i can only see those No options when tweaking "graphics" in the winecfg did anything to address the issuee I had to downgrade to 11.12-1 where this is not happening -- Do not reply to this email, post in Bugzilla using the above URL to reply.
