http://bugs.winehq.org/show_bug.cgi?id=58509 Bug ID: 58509 Summary: AppDB solution to redundant query and storage of Bugzilla versions list per user session Product: WineHQ Apps Database Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: appdb-unknown Assignee: wine-bugs(a)winehq.org Reporter: wineryyyyy(a)gmail.com Distribution: --- Spawned from merge request addressing bug report: https://gitlab.winehq.org/winehq/appdb/-/merge_requests/23 https://bugs.winehq.org/show_bug.cgi?id=58471 Bug Link Queue is broken @jnewman raised server side concerns about redundantly querying and storing Bugzilla version per user session. A quick fix patch is currently in place to resolve the 500 error, but a better solution that queries and caches the Bugzilla versions server-wide and shared between user sessions was requested as a more optimal solution. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Would like to have either a possibility to choose the order or this list should be in alphabetical order 2.) The "Maintainer box" should be before the list of monitored applications. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 45221] New: AppDB: "Your Version" column in maintained apps doesnt show word "staging"

https://bugs.winehq.org/show_bug.cgi?id=45221 Bug ID: 45221 Summary: AppDB: "Your Version" column in maintained apps doesnt show word "staging" Product: WineHQ Apps Database Version: unspecified Hardware: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: appdb-unknown Assignee: wine-bugs(a)winehq.org Reporter: havran.jan(a)email.cz Distribution: --- "Your Version" column in "Maintainership Overview" menu doesnt show word "staging", while "Current Version" column does (for staging releases even if "your" test result is the latest (current) one). It happens for example for these versions maintained by me: Vietcong (MP Demo FistAlpha) [1], Air Missions: HIND (Steam) [2]. It is confusing, because it looks like I posted test result with "testing" version and after that someone else posted test with the same version, but "staging" in this case, which is not true.

[Bug 43702] New: No comments shown if no maintainers for app

https://bugs.winehq.org/show_bug.cgi?id=43702 Bug ID: 43702 Summary: No comments shown if no maintainers for app Product: WineHQ Apps Database Version: unspecified Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: appdb-unknown Assignee: wine-bugs(a)winehq.org Reporter: azrdev(a)qrdn.de Distribution: --- If an app has no maintainers, it shows "comments disabled", and one cannot enter new comments. This is useful, because no one would moderate them. However, it would still be useful to see the backlog of old comments, which may contain hints and workarounds posted by users (when there still were maintainers). -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 56314] New: MPEG-1 video playback does not properly resize screen

It should be fullscreen. Ultima IX has MPEG-1 based video playback that is now working thanks to https://bugs.winehq.org/show_bug.cgi?id=9127 being fixed. Thanks for everyone who helped out there! However, now the video playback only appears in the upper-left corner of the screen. It isn't clipped, but it looks like the system is failing to change screen resolution. These videos playback fullscreen on Windows. See attached for a visual. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59506] New: IMFMediaEngine video playback fails: no MFT_CATEGORY_VIDEO_PROCESSOR registered for NV12→RGB32 color conversion
