[Bug] Fedora 44 RPM incompatible with KWin 6.8.2

[Nilloow]

Description

The PlasmaZones daemon starts and registers its shortcuts, but window placement does not work. The compositor bridge fails because both Fedora 44 RPMs (3.5.3-1 and 3.5.3-2) contain a KWin 6.7.5 effect, while the system runs KWin 6.8.2. Rebuilding v3.5.3 locally against KWin 6.8.2 resolved the problem without source-code changes.

Successful workaround:

I rebuilt the official PlasmaZones v3.5.3 source using rpmbuild and the upstream RPM spec, with kwin-devel-6.8.2-2.fc44 installed. No source-code modifications were necessary.

The resulting RPM contains org.kde.kwin.EffectPluginFactory6.8.2 instead of org.kde.kwin.EffectPluginFactory6.7.5.

After installing the locally rebuilt RPM and logging out and back in, PlasmaZones worked again. All existing layouts, rules and shortcuts were preserved.

Suggested fix: Rebuild and publish the Fedora 44 RPM against KWin 6.8.2 and verify the embedded plugin IID before release. The RPM dependency kwin >= 6.7.0 does not prevent this incompatibility.

Expected Behavior

PlasmaZones should load its KWin effect and provide working window placement after installation on Fedora 44 with KWin 6.8.2.

Steps to Reproduce

1. Run Fedora 44 with KWin 6.8.2.
2. Install PlasmaZones 3.5.3-1 from COPR or 3.5.3-2 from the GitHub release.
3. Log out and back in.
4. Try placing a window in a zone.
5. Observe that window placement fails because the compositor bridge does not register.

Thanks for the detailed report and for checking the plugin IID, that made this quick to track down.

The automatic rebuild for KWin 6.8.2 did run. The GitHub release v3.5.3-r3 has a Fedora 44 RPM built against 6.8.2, and COPR rebuilt too. The COPR build kept the version 3.5.3-1 though, so dnf saw it as the package you already had and never offered it as an update. That's fixed in #1180 and applies from the next release on.

To get a working build now, either of these will do it:

sudo dnf reinstall --refresh plasmazones

which pulls the 6.8.2 build COPR is serving now, or install plasmazones-3.5.3-3.fc44.x86_64.rpm from the v3.5.3-r3 release. Your locally rebuilt RPM is also fine to keep, since it's the same source.

Fixed in 3.5.4 (#1180). COPR builds from 3.5.4 on carry the rebuild revision in the package, so dnf offers a rebuild after a KWin update. Closing this, but reply here if you still see it on 3.5.4.

Thanks for the quick response and the fix! I hadn't expected this to be picked up so quickly.

PlasmaZones has become one of my favourite parts of my KDE setup, so I'm glad I could help track this down.

Thanks for your great work.
