Fedora 41 - KDE strange performance issues

,

Hello there.

I have an issue with my installation and I am out of ideas on what to do about it. I struggle with this for about 3 or 4 months. It’s not hindering me but it is annoying (you’ll see why) so I am looking for ways to fix it.

The problem is that there seems to be some sort of a problem with my installation/configuration which causes KDE to perform awfully in some scenarios:

  • After logging in SDDM then the splash screen appears and it takes around 2 minutes to a fully working desktop. What is strange is that I am able to open the workspace switcher in the upper left corner and launch applications that way, however I cannot see them until KDE is finished loading. Strange markings appear on the current workspace when I do that (some blurred red text appears very quickly). :smiley:
  • After the launch is complete opening Dolphin is also very slow. Every time a new window opens it takes 10 seconds (it isnt a lot but it used to be very fast and open instantly).
  • In Dolphin executing search freezes the app for around 30 seconds and any search string that should result in at least one item also take the same amount of time. Only when I enter some gibberish will it work fast but since nothing is being hit I assume it just does nothing.

Something that I noticed after two installations (first run) is that there was this weird notifications about akonadi migration agent that wouldn’t disappear but was gone after a restart.

This issue started appearing for me sometime in Fedora 40 installation which I tried to fix with an upgrade to F41, which didn’t help. I’ve done clean installation twice, both with encryption enabled and disabled (with a new user so it wouldn’t use the old user configuration, clean slate). Right now the encryption is enabled.

There is also an issue with sudo taking a lot of time to initialize, but I have no idea if that is related (I’ve already tried to add the hostname to the hosts file which didn’t help). Just mentioning that in case it would be connected.

Configuration of the machine:

Operating System: Fedora Linux 41
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.1
Kernel Version: 6.12.9-200.fc41.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 32 × AMD Ryzen 9 7950X3D 16-Core Processor
Memory: 61.9 GiB of RAM
Graphics Processor: AMD Radeon RX 5700 XT

System and home are both on the same SSD which is still relatively fresh.

Thank you!

Look in the system and user journals for errors.
Maybe the slow down is because the system is recovering from a hardware issue.

Maybe it’s caused by mesa? I think there were also issues with some kernel versions and AMD GPUs.

I’ve looked right after logging in and I saw the log massively spammed by the following entry:

kwin_wayland[4653]: No QSGTexture provided from updateSampledImage(). This is wrong.

This appeared 4331 times in the log. Seems like the culprit at least for the long login. I have to find the source of it.

As for the mesa issue it seems it is something different. My issue appears only in kde specific actions. Gaming, videos, basically anything else is not impacted and resource usage remains low.

Edit: Nevermind it doesn’t look like it matters. What bothers me is this:

Jan 29 20:31:18 desktop-cutebyte.home plasma_waitforname[13957]: org.kde.plasma.waitforname: WaitForName: Service was not registered within timeout
Jan 29 20:31:18 desktop-cutebyte.home systemd[4370]: dbus-:1.2-org.kde.KSplash@3.service: Main process exited, code=exited, status=1/FAILURE
Jan 29 20:31:18 desktop-cutebyte.home systemd[4370]: dbus-:1.2-org.kde.KSplash@3.service: Failed with result 'exit-code'.

Can’t find any reason for it to fail though. :smiley:
