[Bug 60129] New: strftime missing support for %O modifier (breaks Python 3.15 calendar module)

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=60129 Bug ID: 60129 Summary: strftime missing support for %O modifier (breaks Python 3.15 calendar module) Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: msvcrt Assignee: wine-bugs(a)list.winehq.org Reporter: te5212329(a)gmail.com Target Milestone: --- Distribution: --- ================================================================================ WINE BUG REPORT DRAFT ================================================================================ Title: strftime missing support for %O modifier (breaks Python 3.15 calendar module) Product: Wine Component: msvcrt Version: 11.14 (also affects 9.0, 10.0) Summary: -------- Wine's strftime implementation does not support the %O modifier for alternative date/time representations. This causes Python 3.15+ to crash when importing the calendar module. Steps to Reproduce: ------------------- 1. Install Python 3.15.0b4 Windows embeddable package in Wine 2. Run: wine python.exe -c "import calendar" Expected Result: ---------------- calendar module imports successfully Actual Result: -------------- Traceback (most recent call last): File "<string>", line 1, in <module> File "calendar.py", line 156, in <module> File "calendar.py", line 110, in __getitem__ ValueError: Invalid format string Technical Details: ------------------ Python 3.15 (commit 438cbd857a875efc105b4215b1ae131e67af37e1, July 31, 2025) added support for standalone month names using the %OB and %Ob format specifiers in the calendar module. These specifiers are part of the POSIX strftime extension for alternative representations and are supported by Windows via GetLocaleInfoEx with LOCALE_SMONTHNAME* variants. The %O modifier is used for: - %OB: Standalone full month name (nominative case for Slavic/Baltic/Greek languages) - %Ob: Standalone abbreviated month name Wine's dlls/msvcrt/time.c strftime implementation lacks handling for the %O modifier, causing it to return an error instead of the month name.

[Bug 60128] Problem with resizing X11 decorated windows in Linux Mint Cinnamon (Muffin WM)

by WineHQ Bugzilla

A "*" is printed after the window number of the client window to make it easier to identify in the list. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 60128] New: Problem with resizing X11 decorated windows in Linux Mint Cinnamon (Muffin WM)

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=60128 Bug ID: 60128 Summary: Problem with resizing X11 decorated windows in Linux Mint Cinnamon (Muffin WM) Product: Wine Version: 11.13 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)list.winehq.org Reporter: empcomputer(a)outlook.com.au Target Milestone: --- Distribution: --- Created attachment 81701 --> http://bugs.winehq.org/attachment.cgi?id=81701 Notepad after launch - OK Running Linux Mint 22.3 Cinnamon. If window manager decorations are enabled and a window is resized/maximised/restored, mouse coordinates are reported incorrectly, resulting in an offset between the on-screen cursor position and hit point. Also manifests as a menu activated by keyboard accelerators appearing in incorrect position. I have found that, under certain conditions (can't see a clear pattern, but seems to depend on window position and size), the window manager triggers ConfigureNotify events for the client window before the parent (frame) window. When this happens, the X11 driver computes the window rectangles using the old frame coordinates, leading to the offset problem described earlier. If window manager decorations are disabled, the problem does not occur (there is no frame window in that case). Simple repro steps: - Ensure that "Allow the window manager to decorate the windows" and "Allow the window manager to control the windows" options are checked - Ensure that "Emulate a virtual desktop" is UNchecked - Launch Notepad - Position the window approximately in the centre of the screen (away from the top-left corner) - Maximise the window - Pull down a menu using the keyboard (e.g. Alt+F or Alt+H) - Note that the menu appears away from the expected position - If you restore the window, you'll notice a similar effect (with reversed offsets) - Moving the window using the title bar corrects the coordinates The problem was first noticed in Wine 11.13, but testing shows that it goes back as far as ~10.0. It is more pronounced/consistent in 11.13, but can be triggered sporadically in some earlier versions as well. After looking through the code and some experimenting, one possible fix is to modify the "host_window_map_point" function to use XTranslateCoordinates. I'm not sure if it's the best solution; I imagine there's a good reason it was coded the way it is (e.g. performance issues due to X protocol overhead - I haven't looked into it enough). I hope I have at least provided a good starting point. I'll also note that I have tested it with a few other window managers (Xfwm, Metacity and Compiz, running Linux Mint 22.3 Xfce Live ISO in VirtualBox) and they did not exhibit the same problem.

[Bug 60125] Yabridge overlaping windows on some WM produce dead zone for input

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=60125 --- Comment #3 from gogokily(a)gmail.com --- Created attachment 81700 --> http://bugs.winehq.org/attachment.cgi?id=81700 Video of the problem In x11 space plugins are created at 0,0 xy so they overlap there and this deadzone is produced. Regarding logs. What kinda of log do you need? No errors are comming thru. I did WINEDEBUG=+relay,+seh,+tid reaper but for those two plugins its over 1gb size, compressed its 35mb. Do you want that log over google drive or something? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
