[Bug 58420] New: Wine crashes when running msys2 iff CPU's PKU/PKRU feature is enabled
by WineHQ Bugzilla 16 Aug '25

16 Aug '25

http://bugs.winehq.org/show_bug.cgi?id=58420 Bug ID: 58420 Summary: Wine crashes when running msys2 iff CPU's PKU/PKRU feature is enabled Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: pipcet(a)protonmail.com Distribution: --- This is a heads-up about a bug in cygwin/msys2 which may be misreported as a wine bug. The Cygwin code assumes CPUID leaf 0x0d to indicate in EBX a 64-byte-aligned value. That may or may not be true on current Windows systems, but on current Linux systems running Wine, with recent CPUs, a CPU feature called "PKU" or "PKRU" (memory protection keys for userspace), enabled by default, indicates an additional 8-byte XSAVE area. This makes the Cygwin code attempt to xsave to a non-64-byte aligned area, which causes a segfault and abnormal program termination. While this is clearly a bug, it's a bug that apparently cannot be triggered by current Windows systems. This means Wine fails to be bug-for-bug compatible in this case. I don't think there's an easy way around that: we'd have to trap XGETBV and CPUID instructions to pretend that a feature that is enabled by Linux actually isn't available. It would have been nice if the Linux kernel had provided a way to disable the pku feature on a per-process basis, but AFAICT, it didn't. The nopku kernel command line argument makes things work, but requires a reboot and disables the very useful PKU feature for the entire system. So I don't think there's a good workaround here, but maybe we should suggest to the Linux kernel people to allow per-process activation of any future XCR0 features? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 58506] New: Some VST plugins using OpenGL don't render in WOW64 mode (black screen)

http://bugs.winehq.org/show_bug.cgi?id=58506 Bug ID: 58506 Summary: Some VST plugins using OpenGL don't render in WOW64 mode (black screen) Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: opengl Assignee: wine-bugs(a)winehq.org Reporter: a.oleinic103(a)gmail.com Distribution: --- When using yabridge to run Windows VST plugins in a native Linux DAW (in my case, REAPER), Waves plugins do not render correctly, showing a black window. The window is interactable (grabs the cursor, can change settings, etc), but dragging it, closing and re-opening, etc. does not work. In the logs, the plugins show a bunch of OpenGL errors. This is specifically a WOW64 regression, since using a build of Wine 10 without WOW64 works fine. This is what it looks like: 09:07:42 [WaveShell1-VST3 14.12_x64-09EFPegt] [Wine STDERR] 0024:err:opengl:null_glEnable unsupported 09:07:42 [WaveShell1-VST3 14.12_x64-09EFPegt] [Wine STDERR] 0024:err:opengl:null_glBlendFunc unsupported (Sorry for pasting it here, I have read the rules, but it's not letting me paste text as an attachment for some reason :/) -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 2082] DirectDraw games only showing black screen

http://bugs.winehq.org/show_bug.cgi?id=2082 --- Comment #180 from Saulius K. <saulius2(a)gmail.com> --- (In reply to chaosesqueteam from comment #176) > In my linux mint install from 2015 Diablo 1 works fine. > In my Debian install from 2012 Diablo 1 works fine. > In my Devuan install from 2018 Diablo 1 works fine. > In my Debian server from 2003 Diablo 1 works fine. I am the original reporter. Diablo 1 did not work for me anytime I tested it during these years (which occurred like dozen of times – it wasn't continuous process). Other users reported the same. If you're are lucky to have working setups, please report the distro and the Wine versions + the GPU model you run your X11 on here. In 2003 the implementation was called XFree86, circa since 2004 it's Xorg. I guess there might have been some regression namely due to this change. So I'd say let's skip the 2003 setup for now. And please stop the noise (flooding), and let's get technical. :) S. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
