[Bug 43124] New: FlashWindowEx: WM_NCACTIVATE behavior is incorrect

https://bugs.winehq.org/show_bug.cgi?id=43124 Bug ID: 43124 Summary: FlashWindowEx: WM_NCACTIVATE behavior is incorrect Product: Wine Version: unspecified Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: user32 Assignee: wine-bugs(a)winehq.org Reporter: gamax92(a)aol.com Distribution: --- Created attachment 58328 --> https://bugs.winehq.org/attachment.cgi?id=58328 FlashWindowEx dwFlags parameter tests Depending on the dwFlags parameter, FlashWindowEx may send a WM_NCACTIVATE message with the wrong wParam value. Some flags should not send a WM_NCACTIVATE message at all. Attached is a document I've made from testing FlashWindowEx with various flags and having the window active/inactive. This issue seems to be related to Overwatch losing focus on respawn, it calls FlashWindowEx with dwFlags = 0xE (FLASHW_TIMERNOFG + FLASHW_TRAY), which according to my tests should send a WM_NCACTIVATE message with 1, but wine sends 0 instead. Forcing FlashWindowEx to send TRUE instead did resolve the loss of focus. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 49195] New: Multiple 4k demoscene OpenGL demos crash on startup (failure to lookup atom 0xC019 'static' from global atom tables)

https://bugs.winehq.org/show_bug.cgi?id=49195 Bug ID: 49195 Summary: Multiple 4k demoscene OpenGL demos crash on startup (failure to lookup atom 0xC019 'static' from global atom tables) Product: Wine Version: 5.8 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: user32 Assignee: wine-bugs(a)winehq.org Reporter: focht(a)gmx.net Distribution: --- Hello folks, extracted from bug 48898 My comment: https://bugs.winehq.org/show_bug.cgi?id=48898#c12 --- quote --- To me it looks like bug 18490 ("Multiple games fail to set pixel format on D3D device context created on desktop window (Empire: Total War, Napoleon: Total War, Utopia City)") but for GL device context on the desktop window. According to online information it's not allowed to do any rendering using this context but enough to call functions like glGetString() etc. Maybe some of the Wine graphics folks could weigh in with an opinion if this limitation is already known / tracked in a bug? --- quote --- Henri's answer: https://bugs.winehq.org/show_bug.cgi?id=48898#c13 --- quote --- I'm not aware of an existing bug report for this issue, no. It does strike me as similar to bug 36506 though, and it would not particularly surprise me if wglGetProcAddress() is supposed to return results consistent with GL_EXTENSIONS/GL_VERSION here, even without a current GL context. I seem to recall having established in the context of bug 18490 that creating a GL context (or more specifically, setting a pixel format) on the desktop window is indeed supposed to fail. In any case, this seems like of of those bugs that would benefit from tests to establish what's supposed to happen. --- quote --- Turns out this was a side-effect of an earlier problem.

[Bug 58515] New: Street Chaves only displays a black screen (regression)
by WineHQ Bugzilla Oct. 3, 2025

Oct. 3, 2025

http://bugs.winehq.org/show_bug.cgi?id=58515 Bug ID: 58515 Summary: Street Chaves only displays a black screen (regression) Product: Wine Version: 10.11 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: denilsonsa(a)gmail.com Distribution: --- Wine versions up to 9.7 were able to render the game graphics correctly. Now I tested again on Wine version 10.11 and all I get is a black screen. The game seems to be working, because I can blindly press "Z" to confirm, then "5" to insert credits (and hear the sound effect), and "1" to start, an "Z" a couple of times to select my character and advance to the actual fight… After all of this, I can hear the in-game music and the in-game sound effects of the fight. I just can't see any of it due to being pure black. How to reproduce? 1. Get the game archive from https://archive.org/details/street-chaves-1.5-a 2. Unpack it anywhere, and run `wine Chaves.exe` 3. After a few moments, a black window without any decoration will show up. Having no decorations is normal expected behavior. Having it completely black is a bug/regression. Tests? The game works fine under "Proton Experimental" on the Steam Deck, but I don't know exactly what is the Wine version. It also works fine under "Proton 10.0-1 (beta)". It does NOT work (black screen) under Wine 10.11 on Manjaro Linux. It does NOT work (black screen) under wine-ge-8-26-x86_64, which is the default Wine runner for Lutris, installed from Flatpak. https://lutris.net/games/street-chaves/ Other Wine versions are untested. If you are testing other versions, please be aware that older versions had a problem with keyboard input. You could see graphics on the screen, but you couldn't progress any further. This has been solved in bug 52738. -- 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.

Product: Wine Version: 10.7 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: hibbsncc1701(a)gmail.com Distribution: --- Created attachment 78512 --> http://bugs.winehq.org/attachment.cgi?id=78512 Screenshot of winecfg audio tab UI bug. Under Wine-10.7 (specifically the winehq-devel packages for Debian), the winecfg Audio tab doesn't seem to be functional even in a clean wine prefix. There is no drop down for selecting audio drivers, and the currently selected driver says "(None)". The output and input device selection drop down boxes all say "(System Default)" with no other options given. The speaker configuration is completely blank, and speakers drop down is empty and disabled. The only thing that does seem to work is the "Test Sound" button which does play a test sound, when clicked. Manually selecting an audio driver (such as winealsa) using the helpful registry key (HKCU->Software->Wine->Audio) does appear to work, but results in no visible changes to winecfg. (The change can only be observed from WINEDEBUG="+mmdevapi"'s console output.) Even when shutting down pulseaudio / pipewire (systemctl stop and systemctl disable), which _should_ just leave us with alsa, there are no visible changes in winecfg, and the test button still works. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
