Sudden freezes while using the system

Hi!
I’m experiencing an issue where my system suddenly freezes for a moment and then recovers. This started after the Plasma 6 update. I checked my memory usage it was nowhere near 100% so the system shouldn’t be running our of memory. I’ve had this happen for example while scrolling through news articles, typing commands to the terminal, writing… etc. It can happen anytime regardless of the system load. I didn’t see any helpful information in journalctl.

My system:

Similar problem, so I think adding in a reply would be justified instead of a new post. My OS runs on these hardwares-

Intel Core i3-4130 
4 GB RAM 
Intel HD Graphics 4400

while it does run smooth and optimal for 10 mins prior to startup, it starts lagging after a short while, even completely freezing the processes at one point. I am running the latest version of KDE Neon and Plasma.

In case relevant, Usual apps are Discord, Spotify and two tabs of browser.

Some users have used a workaround for this (or similar effects) by switching to the X11 session instead of using Wayland.
This is possible e.g. at the log-in screen in the lower left corner where you can choose the session type.

You could try if this reduces the lags…

I did try with session switch, but it still results in the same outcome

I have the same issue on X11 since the KDE 6 update. On Wayland, it was much worse. I was getting frequent crashes. I’m using Intel HD Graphics.

Yeah, I too tried both X11 and Wayland. The problem still exists… Also there are other bugs I encounter while using X11. Such as this one:

Same issue with occasional stuttering in a KDE Neon after updating to 6.0 and switching to Wayland, even though overall the system became significantly faster.

I’m getting the same issue on a fresh install.

I’m not sure but could this be related to the other display manager problems out there? Seems like only the display freezes and not the whole system…

Hello,
Idem, freeze of the system in a completely random way on new install of neon!

Maybe it has something to do with the different Wayland problems I’m having?

Yes. I’m also suspecting that it could be related to the other Wayland problems. Something is not working right with it and it’s causing the display server to crash from time to time and not show the graphics correctly…

So the problem lies with the new major update, I don’t know if this is really the issue, but sometimes when the screen gets frozen, the window loses focus and stops taking any clicks to it’s elements. Sometimes it all went smoothly when I clicked the border of the window.

Now, I switched to BigLinux to test things out, BigLinux uses 5.2.x Plasma version with Manjaro. It has lightning fast responses and works like a proper desktop.

There were supposed to be fixes in the 6.0.x version patches, but am not sure, I couldn’t install them through the software updater, do I need to run a clean install everytime a new version comes?

Hello,
I can confirm that Wayland is indeed buggy, I switched to X11 and let my machine run with a video loop for 24 hours without any problem!

According to this thread, the problem has been fixed in Plasma version 6.0.2 OP could close the thread as solved if they want

I just updated Wayland 6.01 to 6.02 and no luck for me, it’s still buggy :frowning:

Just for confirmation, you did update the system packages, yes?

I applied the updates that the system notification suggested.
nothing else to do?

nothing proposed with this command :frowning:
sudo pkcon refresh

Common solution could be updating your graphics drivers, or check the system logs for troubleshooting

I installed system update to Plasma 6.0.2 and after all day working/using - there is no freezing any more. But I use X11 session, I don’t use Wayland session because its messing with apps windows started from saved session. X11 session remembers correctly running apps and their windows sizes and locations on the screens (I use external monitor connected to my laptop).
