KDE desktop performance issues after last update (8th June'21)

Hi everyone,

I’ve been using Manjaro KDE in my Lenovo Thinkpad E14 for the last month and I was very happy with the system performance (even with several apps open at the same time like Firefox, Thunderbird, Kile, Okular, Atom, Spotify…)

However, after the last update in 8th June’21, I’m experiencing global performance issues even if I have only one app running. The system have just become slower and you can feel it in windows animations, pdflatex compilations or whenever you load websites in Firefox, messages in Thunderbird or pdf in Okular.

Here is my computer info:

(Also, now “kded5” ask for access in “kwallet” every time I reboot the system)

Is someone experiencing the same issues? Let me know, thanks!

Hi @Sr_J ,
Welcome to the forum. Could you try this?
System Settings->KDE Wallet Unclick the button that says “Enable the KDE Wallet subsystem”

Y can also remove kwalletmanager package after disabling kwallet in systemsettings but not the other related packages (kwallet, signon-kwallet-extension).

Hope this help, regards,

Thanks @j8a. I don’t know how, but it seems that a simple:

sudo pacman -Syu

has fixed the problem somehow, since several pacman related packages have been downgraded:

[2021-06-10T00:19:00+0200] [ALPM] downgraded pamac-snap-plugin (10.1.2-0.1 -> 10.0.6-2)
[2021-06-10T00:19:00+0200] [ALPM] downgraded pamac-gtk (10.1.2-0.1 -> 10.0.6-2)
[2021-06-10T00:18:59+0200] [ALPM] downgraded pamac-flatpak-plugin (10.1.2-0.1 -> 10.0.6-2)
[2021-06-10T00:18:59+0200] [ALPM] downgraded pamac-cli (10.1.2-0.1 -> 10.0.6-2)
[2021-06-10T00:18:59+0200] [ALPM] downgraded pamac-common (10.1.2-0.1 -> 10.0.6-2)

Now, my computer’s performance is back to normal, and there is no more dialog of “kded5” asking for access in “kwallet”. :man_shrugging:t4:
