This is probably because of something that you are doing. But I am unable to guess what.
I’ll just note that I set my desktop to startup from a saved session. Then I set it up the way that I like, and save that session.
The default it for Plasma to save things as you logout, and restore them on login. So what you get depends on what your desktop looked like at your last logout.
Yes, I have always had it set to restore previous saved session, but let me see what happens when i start with an empty session.
Also, check out this other issue. I made a video showing the lag issue that’s been going on this week.
jonzn4SUSE here… back at it again with another video. ;D
In this video you will see Plasma responding normally and then I’ll make a change and you see the lag start.
Again, to fix the issue I have to change my desktop session to start with an empty session.
[FONT=monospace]Just noticed that lag issue affects both regular users, but not root.
When logged in as root, I can make the same desktop changes as the regular user with no issue.
I can log out of the regular user(lag issue) and then into root, log out of root and back into the regular user the lag issue is gone.
If I make the same changes again as the regular user the lag returns.
I’ll make a change and post the result of free and top.
That’s ~/.cache, and everything in it that is kde/plasma-related, if not all. That’s always the first thing to try when Plasma gets strange or otherwise misbehaves. It must be done while not logged into Plasma. Do it from an IceWM session, or from a vtty or a root login.
That image shows TW20200917. Could it be that some old QT/KDE/Plasma packages remain installed, or an optional repo is creating runtime conflicts noted in the logs?
zypper --no-refresh se -si | grep 'tem Pac' | grep -v plication
zypper lr -u
That’s just an image of what my desktop looks like before all the issues started last week. KDE keeps forgetting my session and bringing up this desktop instead that I never set before.
So just last week is when you upgraded TW from 20200917 to 20210222? I still suggest to check for stale packages.
You should also try IceWM (and/or any other installed session type) to see if you encounter any lagging. That will limit the problem location to either the Plasma session itself and its autostarts, or something deeper.
