KDE Plasma very slow, sluggish, unresponsive

Hello. Last friday I installed the KDE edition Manjaro on my desktop computer.
I run six 1440 line monitors on two AMD rx480. Processor is Ryzen 2700x.
Most of UI runs very slow. The main menu takes a few seconds, to type in textboxes lags few seconds. Chrome is VERY slow when I type or scroll, while Firefox runs pretty much ok in terms of speed but tabs act funny like they are sometimes not where they seem to be.
Konsole seems to run fine.

I have tried changing opengl version and disabling composer and I don’t see any change.
I’m not sure if I’m running open or proprietary drivers.
What should I be trying?

Windows 11 out of the box without any manual graphic driver installation work perfectly fine.

Hello,

Check the compositor if enabled and set to OpenGL3.1 (in case you are on KDE Plasma before 5.24) … and might want to reduce some of the animations effects.

I already tried that. Setting OpenGL 3.1 and nothing changed.
Is it really that heavy? I disabled the composer (the checkbox to start it with the system) and I don’t see any change, also.
What should I be trying to change?

See below:

Might have to log out and back in … If you provide more info, as pointed out by @ishaanbhimwal - we might figure things out. Probably you have baloo_file running and that can do some funky stuff sometimes … and in case of a HDD compared to a SSD, that can affect things more obvious.

I have an SSD and I have of course been resetting after every change.

Umm if this is the case, that is very bad and should be fixed.
It is a repartitioned SSD, used before with all partitions new.
I have dual boot with windows 11 and no problems whatsoever on windows.
I confirm once again Firefox and Konsole work normally. Dolphin is ok too.

Main menu takes a few seconds every time. Results in menu search take seconds along with what I typed to appear.
Settings app takes a long time to appear and when I type ionto the search box it takes a long time to see what I typed. By long, like 5 seconds. Same with whatever I click in settings app. Chrome installed from AUR is unusable. I was barely able to take a screenshot, it took me more than a minute to capture rectangular region.

I quickly tried onlyoffice writer and works super quickly and perfectly.
Slack installed as flatpak works terribly. Slow response to keyboard, resize window takes ages…

this is the first time that you are talking about the use of flatpack. that’s a total different story than kde.

Sorry, I am not that into technicalities.
Otherwise KDE settings app is laggy and other stuff to what I already mentioned.
Liek that screenshot where you can change the OpenGl version. Click, wait 3 seconds, clikk other opengl version, wait 4 seconds, click apply, wait 5 seconds…
Anyway I also have Manjaro KDE on two laptops and have zero issues there with all the same programs.

Hi @mandor
I hope I am not too late!
I have been through this. As @bogdancovaciu mentioned it may be baloo.
It happened with me because I was using some “snapshoting” software that takes sanpshots from time to time of my system including data files, pdf, doc,… and baloo keeps re-indexing each snapshot which caused it to be working all the time.
Problem not encountered after I did not instll any snapshoting software.

Hint:
Create a text file with a unique name, type just anything inside. Wait for it to get indexed, and wait for it to be reindexed if you have snapshoting.
Searching for this file by name or content should give you more than one result, all pointing to the same file.
If so, then the problem is with snapshoting as above.
I hope this helps and i am not to late, and hope this helps others in case they have same problem.
