[Bug 59435] New: No windows elements categories (in Construct 2 r280, probably generic problem)

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59435 Bug ID: 59435 Summary: No windows elements categories (in Construct 2 r280, probably generic problem) Product: Wine Version: 11.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: gsw.eugeneulan(a)gmail.com Distribution: --- Created attachment 80409 --> http://bugs.winehq.org/attachment.cgi?id=80409 3 images combined for bug description There are no elements categories in Construct 2 editor windows where they should be. Instead of expected categorized views for plugins, behaviors, effects, events and expression dictionary (where I've noticed it so far) they are all displayed as a whole in their own window, making navigation and selecting the correct item harder. I'm naming it "probably generic problem" as I've noticed it in the Construct Classic's insert object dialog as well, and I suspect that every Windows program making use of this exact element has the same issue, as it is may not be fully implemented in Wine's code. To see reproduced problem in application itself: 1. Install the latest Wine development version (11.3) along with Mono & Gecko dependencies (as it has requested me to do); 2. Download the latest ever Construct 2 installer from this direct official link: https://downloads.construct.net/construct2/261/construct2-r280-setup.exe SHA-256: f331a31320be71135bfb0df0bf6b7442fe416062bdf726b436120dbfa0a20338 3. Run the installer in default Wine prefix and follow through all wizard's steps; 4. After program runs for the first time, you can select any "Check for updates" setting if requested (personally I select "Don't check" as the program has no official support either way) and create a new project (one quick way to do so is press Ctrl + N, then Enter); 5. You can now call one problematic dialog right away. Either double-click somewhere on the layout, or right-click and choose "Insert new object"; 6. See and compare observed and expected results on the attached screenshot! -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59333] VNyan leaks memory (race in __wine_syscall_dispatcher $rsp switching breaks Unity GC)

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59333 Madalee <madalee(a)ohlmeyers.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |madalee(a)ohlmeyers.com --- Comment #18 from Madalee <madalee(a)ohlmeyers.com> --- We wanted to report that we've seen this same behavior in Warudo (also Unity based vtuber software) in all version after Proton-8. This leak usually doesn't happen quickly, though we've seen apps leak in as little as an hour, we've seen it not manifest until around 30 hours. We believe we've seen this in other unity games as well. Basically, anything unity that we run on Linux through Proton newer than 8 seems to leak... eventually. As Hoshino Lina pointed out, the common thread among vtubers is that we often stream for many hours. We think this extended time with Unity is why it tends to affect us more than most users and why this very serious bug often goes unnoticed. Not sure how this is for other users, but for us when a Unity app does this, our whole system hangs, sometimes for several minutes while we wait for the memory goblin to rescue us by killing apps. We're happy to provide any additional details that can help, or run testing/debug versions of Wine and provide logs. Thanks, -Madalee -- 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 59434] New: mozglue bypasses NtCreateThreadEx, leading to uninitialized x87/SSE FPU state and SIGFPE (0xc000008f) in Gecko

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59434 Bug ID: 59434 Summary: mozglue bypasses NtCreateThreadEx, leading to uninitialized x87/SSE FPU state and SIGFPE (0xc000008f) in Gecko Product: Wine-gecko Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: wine-gecko-unknown Assignee: jacek(a)codeweavers.com Reporter: Cruzer19993(a)gmail.com Distribution: --- Created attachment 80407 --> http://bugs.winehq.org/attachment.cgi?id=80407 Combined winedbg showing info about FPU settings of gecko thread, svg rendering thread, and backtrace In wine-gecko, mozglue creates threads by calling the host's pthread_create directly instead of going through Wine's internal thread management (NtCreateThreadEx). Because these threads are spawned outside of Wine's lifecycle management, they do not receive the standard Windows FPU environment initialization. Specifically, new threads inherit the host's default Linux FPU state rather than the Windows-standard FPU Control Word (0x037f) and MXCSR (0x1f80). When Gecko’s layout engine (xul.dll) performs transcendental math operations (such as FSINCOS), it triggers a SIGFPE (translated to a 0xc000008f Inexact Result exception) because the precision exceptions are not correctly masked. Steps to Reproduce: Run an application utilizing wine-gecko with Direct2D SVG rendering enabled (e.g., Solid Edge 2026 Ribbon UI). Trigger a complex SVG render or layout calculation that invokes transcendental math instructions in xul.dll. The application will crash with 0xc000008f (Inexact Result) or a SIGFPE when a math instruction is executed on a thread spawned by mozglue. Actual Result: Threads created via mozglue have uninitialized or "dirty" FPU status/control flags, leading to catastrophic floating-point exceptions in Gecko components. Expected Result: Every thread, including those spawned by mozglue, should have an initialized FPU state consistent with Windows defaults (0x037f) to prevent exceptions during standard math operations. Proof of Concept / Workaround: I have verified that preloading a custom wrapper to intercept pthread_create and explicitly calling fninit (and potentially ldmxcsr) at the start of the thread resolves the stability issues entirely. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
