This is different from the usual broken apps a la "I failed at porting my 32-bit app to 64-bit" (pointer truncation). In this case, pointers from certain allocations are broken into multiple parts and used as indices into multi-level lookup tables. Pitfall: there is a 44-bit user-mode VA limitation (8TB) for 64-bit Windows which was lifted starting with Windows 8.1+. Wine doesn't respect the 44-bit pre-Windows 8.1 virtual address space limits, allowing process heaps to be placed in 0000'7Fxx'0000'0000 range (128 TB) which causes out-of-bounds access to lookup tables when indices overflow (derived from pointer bits). The exception occurs in entry point, causing 'msxml6.dll' to be unloaded. One workaround is to move Wine's top-down allocations/heaps into 8 TB VA range (Wine preloader) and impose same user-mode address space bits limits as with all 64-bit Windows versions < 8.1 to stay "compatible". I've tested it and it works for native here. Not sure if it's worth to change though. I don't know if a separate 64-bit MSXML6 re-distributable package exists that has been fixed wrt Windows 8.1+ address space limits. MSXML6 is part of Windows OS for newer versions and automatically kept up-to-date. $ sha1sum msxml6_x64.msi 1eb84eeae7729ea5db7fe79779f4e216114261ba msxml6_x64.msi $ du -sh msxml6_x64.msi 2.6M msxml6_x64.msi $ wine --version wine-4.0-276-g84459ba94b Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.

When opening a menu of the developer studio, the menu items with arrows (that open submenus) are not displayed correctly. The triangular arrows on the right end will stick out of the menu popdown area. I'm not sure if they just stick out to the end of the "shadow" (3d effect) around the popdown, or sometimes more. They should be fully contained in the popdown area. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

[Bug 59018] New: Font artifacts on glyphs with overhangs

http://bugs.winehq.org/show_bug.cgi?id=59018 Bug ID: 59018 Summary: Font artifacts on glyphs with overhangs Product: Wine Version: 10.17 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: trivial Priority: P2 Component: win32u Assignee: wine-bugs(a)list.winehq.org Reporter: gamelaster(a)outlook.com Distribution: --- Created attachment 79757 --> http://bugs.winehq.org/attachment.cgi?id=79757 Images of the issue + PoC patch In the game MTA San Andreas (multiplayer modification for GTA San Andreas), in game chat and other parts using relevant API, some glyphs have leftover artifacts (images in attachment). ---------- User vahook from MTA:SA community was so kind that he investigated this issue and found the root cause, with hacky PoC fix provided. Quoting his explanation: >> The DrawText methods in Microsoft's d3dx9 implementation expect the ExtTextOut functions in GDI to opaque overhangs as well (TTF glyphs with a negative abcC value) when invoked with the ETO_OPAQUE option, as DrawText will use abcA + abcB as the glyph width when copying the rasterized glyphs from a (reused) temporary buffer to a texture. However, the current implementation in NtGdiExtTextOutW opaques out an abcA + abcB + abcC wide box, meaning the background behind overhangs won't be cleared, resulting in artifacts in the font texture from previously rasterized glyphs. In the attachment archive, there are images of the bug, also with image of PoC fix applied. PoC Fix patch is there as well. Additionally, there is font texture dump from the game, which shows that the artifacts are present in the texture. Vahook provided reproduction code as well, which I modified a bit to forcefully use d3dx9_42.dll for successful reproduction. The code can be found here: https://github.com/gamelaster/wine-gdi-font-artifact-repro with prebuilt binaries (built by me) available to be downloaded here: https://github.com/gamelaster/wine-gdi-font-artifact-repro/releases/tag/v1.… . -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 54979] New: Futexes which protect memory allocation congest, causing 100x performance degradation
by WineHQ Bugzilla 21 Nov '25

21 Nov '25

https://bugs.winehq.org/show_bug.cgi?id=54979 Bug ID: 54979 Summary: Futexes which protect memory allocation congest, causing 100x performance degradation Product: Wine Version: 8.0.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: nagle(a)animats.com Distribution: --- Created attachment 74518 --> https://bugs.winehq.org/attachment.cgi?id=74518 Debugger output with multiple threads stuck in spinlocks. SUMMARY Under the wrong circumstances, a program doing many memory allocations from multiple threads can experience more than 100x performance degradation. I'm seeing this in my own Rust program, which has 16 sometimes-compute-bound threads on a 12 CPU machine. This works fine on Microsoft Windows and when compiled for Linux. Under Wine, it can be over 100x slower. Multiple threads are banging on a spinlock at _InterlockedCompareExchange [Z:\usr\src\packages\BUILD\include\winnt.h:6630] in ntdll spin_lock [Z:\usr\src\packages\BUILD\dlls\ntdll\sync.c:937] in ntdll This is the spin lock around the queue for pausing threads. DISCUSSION This looks like futex congestion. That's a known kind of problem, but doesn't seem to have been seen in Wine before. It may be that some programs just run really slow under Wine, and nobody knows why. The code in NTDLL is clearly intended to handle the fast case without doing an OS-level lock. Under light load, that's O(1). But under heavy load, with multiple threads pounding on spinlocks, each spinlock waits longer, and there are multiple threads, so it becomes O(N^2). Which means huge slowdowns. See discussion at https://forum.winehq.org/viewtopic.php?t=37688 which has snippets of the code that's causing the problem. I can copy all that info over here if necessary. Let me know. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
