Created attachment 141606 [details] Screenshot of KSysGuard on 5.21.5 (left) and 5.22.5 (right, bug) Since the release of KDE 5.22.0, the processes listed in KSysGuard are missing both the window icon and window title. This issue is not present in KDE 5.21.5. This bug happens in both the stand alone KSysGuard application and System Activity (CTRL+ESC) pop up. STEPS TO REPRODUCE 1. Open KSysGuard 2. Open "Process Table" tab 3. Observe running windowed applications, such as Dolphin, Konsole. OBSERVED RESULT - There is no window icon in the "Name" column. - There is no text in the "Window Title" column. EXPECTED RESULT - The window icon and title is displayed. SOFTWARE/OS VERSIONS Linux Distribution: Arch Linux KDE Plasma Version: 5.22.5, 5.22.90 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION The alternate, newer "System Monitor" application isn't affected. Not sure if they share the same underlying library?
Same here on Arch Linux and Gentoo, same Plasma and KDE Frameworks versions.
I did a git bisect and found the problem started at this commit on the libksysguard repository: 0c76e685e022e8a9648805f8ddc5a2857c9e37bb https://invent.kde.org/plasma/libksysguard/-/commit/0c76e685e022e8a9648805f8ddc5a2857c9e37bb I was able to get it working by reverting that commit (despite fixing something deprecated), resolving the conflict and rebuilding my package locally (in the case of Arch, the PKGBUILD file). Attached is a copy of the diff.
