(In reply to Nate Graham from comment #1) > Then it sounds like a regression in Qt, right? Yes, apparently it is. It's very annoying. There was a similar error recently, also when updating qt6, and I made a bug on this topic here, but I did not find this previous bug. The previous bug was quickly fixed. However, I don't remember it very well.

Confirmed.
Confirmed on EndeavourOS (Arch Linux). Can confirm this bug has been present since the QT 6.11.1 upgrade. It is quite annoying. Furthermore, there are also more bugs out of scope with this one, such as tabs in System Monitor gone missing. A new big issue may be needed for that.

Just ran updates and ran into this issue. Fedora has it as well. Operating System: Fedora Linux 44 KDE Plasma Version: 6.6.5 KDE Frameworks Version: 6.26.0 Qt Version: 6.11.1 Kernel Version: 7.0.8-200.fc44.x86_64 (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i5-6500T CPU @ 2.50GHz Memory: 32 GiB of RAM (31.2 GiB usable) Graphics Processor: Intel® HD Graphics 530
EndeavourOS, same behavior after the update. All the notifications with an "undefined" after the program name doesn't auto close. Examples: "dolphin - undefined" "firefox - undefined" "ark - undefined" Zapzap (flatpak version) is the only one in my system without the "undefined" string, therefore it auto closes.
Experiencing the same bug on my Garuda and also on my Artix both in wayland and xlibre sessions. Saying this as a long time KDE Plasma user: it would be quite fortunate to do some thorough QA tests before releasing something,- things just keep breaking more frequently lately...

I can confirm I get this too. Same versions as Sylens. I can see the following in my log too when I try to compress a file: May 18 10:13:19 steve-desktop plasmashell[3375]: qrc:/qt/qml/plasma/applet/org/kde/plasma/notifications/global/Globals.qml:527:13: Unable to assign [undefined] to bool
