Hmm? I wonder? I will update my Pi 400 and see.
Edit: Had to overwrite that conflicting file but seems okay.
Edit2: I’m using Xfce on the Pi 400 as it won’t run KDE properly for what ever reason. Budgie i think i also tried and was okay too.

I wonder if this performance regression is related to what you saw?

I suspect not as I believe testing is still using Linux 6.0.11.
Did you end up reinstalling? Did it fix it? I can’t imagine it would since you’re essentially ending up with the same “updated” install you would have had from your last install, but I thought I’d ask.
zero problem . can no say about affect on DE’s. my Odroid run a minimal bspwm

I’m having the same problem as well. I have a laptop with Ryzen 3 5300 APU.
The following packages were updated and after downgrading its back to normal
glib2 lib32-glib2 linux linux-headers linux-zen linux-zen-headers python-cairo sqlite usbutils
I don’t know which of them caused it.
Yes, I reinstalled and everything works well. System is fast and does not have any lags it had after that update on previous install. Yesterday I updated my wife’s laptop (HP 250 G Netbook) which had EOS KDE Plasma and there was no problem at all. There must be something about updated packages in my laptop (Lenovo ideapad 5 Pro) with KDE Plasma which caused the mess I got into.
Does your laptop have Intel Graphics? There was a security update for those with 6.0.11. I feel like it might be the cause of it.
No, my laptop has AMD Radeon Graphics. But could it be the kernel version I used? When I reinstalled I chose 5.15.81-1-lts kernel and since then I haven’t had any slowness in my system.
Yes. The kernel could definitely be the issue.
I have two laptops with amdgpu and a desktop. Is your laptop an older radeon chip?

I can confirm the slow down after system update, i thought it was a program i installed for first time but looks like it’s something else
Try downgrading the kernel or installing the LTS kernel.
Did you try that ? and if so did it work ?
I am not having the problem…

ah ok, i’ll try the kernel suggestion, thanks

I could be wrong, but I’m beginning to suspect it might be something to do with CPU frequency/power-saving functioning too aggressively with 6.0.11 for some reason.
This post on Arch hints at the same thing: https://bbs.archlinux.org/viewtopic.php?id=281799
This could be the reason or at least related to it. I use slimbookbattery and slimbookamdcontroller. In Energy Saving mode, the CPU freq was going down as 466Mhz. It’s way too low for the system to operate these days. It wasn’t usable in Balanced mode either. I had to change it to Maximum Performance to make the laptop work properly until I downgraded the kernel.

I was using cpupower set to Powersave for all cores. It was working well until the 6.0.11 update.
