I recently (been about a couple weeks, I think) upgraded my Manjaro kernel to 5.4.89-1-MANJARO
. Everything has been working great.
Until recently, a couple days ago, when for some reason after a few hours of uptime some apps become very unresponsive. Entering text takes 3-4 seconds, scrolling is very laggy, context menu take a few seconds to appear. Only a few handful of apps that I use are affected my this Firefox, quasselclient (Qt), keepassxc. Other apps like chromium, emacs, Krita, gnome-terminal work as usual.
I tried the scientific method to find what could have caused this but nothing worked. The only two things that come to mind are, that I installed KDE plasma recently, and did a sudo pacman -Syu
. However, I have uninstalled all packages associated with plasma but I’m not sure if it added some config which is doing this.
I tried looking into the logs and nothing there is nothing odd in them.
My system config:

Any idea what might be up, where I could at least find logs related to the problem?
