I’m not sure, but it seems there might be some regression with the latest Fedora 44 update with KDE 6.7 and NVIDIA drivers.
Since this last update, I’ve noticed that when playing a game using Proton, the FPS started fluctuating between 60/30 FPS abruptly and randomly, in both DX11 and DX12 modes.
I also noticed the same behavior using Godot Engine Forward+ render.
None of this was happening before the update.
I tried replacing the current driver 595.XX, installed by RPM Fusion, with the latest driver available from NVIDIA on the website 610.43.02, but the behavior remained the same.
Since I need the computer, I decided to install Kubuntu 26.04 LTS and I can confirm that everything is now working correctly with these settings:
I’m on fedora 44 and upgraded. my main system is a vm guest also running fedora 44 and i had to downgrade plasma to prior version as i could not login to the desktop without it hanging and kwin-wayland going compute bound. this is not a good version for me. It run fine on my laptop though which also runs fc44.
Its a touch buggy but should be sorted within the next couple of weeks. On mine, Discover/Update is playing up. It shows packages when there are none. Tells you that its fetching updates, when it clearly isn’t. Was proven by using sudo dnf update.
I am experiencing similar Discover Update issues after KDE Plasma 6.7.0 was installed (showing X# of packages to be updated when there are none).
Then did a sudo dnf update --refresh, which did update 20 packages.
I am on F44 and since the upgrade to Plasma 6.7, my panel and all widgets stop functioning a minute or so after logging in. Dolphin crashes on any right click. When entering the Dolphin settings menu, I found this on STDERR:
kf.kio.widgets: Failed to check which JobView API is supported "Did not
receive a reply. Possible causes include: the remote application did not
send a reply, the message bus security policy blocked the reply, the
reply timeout expired, or the network connection was broken."
I tried dbus-send directly, and got this:
$ dbus-send --session --dest=org.kde.kuiserver --type=method_call --print-reply /JobViewServer org.freedesktop.DBus.Introspectable.Introspect
Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply.
Possible causes include: the remote application did not send a reply,
the message bus security policy blocked the reply, the reply timeout
expired, or the network connection was broken.
And in fact I cannot find kuiserver at all:
$ find /usr/share/dbus-1/services/ -name "*kuiserver*"
(no output)
Shouldn’t that be there? Was this missed in the packaging?
Correct. I meanwhile found that the issue is a little different from what I first thought. dbus-send works fine after logging in, despite kuiserver files not being where I thought they should be.
But what triggers the issue is when I switch to a different Plasma activity. After that my KDE panel becomes unresponsive, dbus-send stops working, and I see those Dolphin crashes.
Regarding this, I’ll be updating the original post, but we did unblock (most) of the gear suite on F43, which will get released at the same time as 6.7.1.
I’m sorry if it’s a wrong place to ask this question - when packaged and tested, will Plasma 6.7 be available trough normal updates channel for F44? I use Kinoite, so kinda crucial here
Found a bug in 6.7.x with Qt 5 applications: all text controls in Qt 5 applications are displayed truncated and end with an ellipsis.
Can be reproduced both on Fedora 44 and 43 in most Qt 5 applications, eg. in GoldenDict (sudo dnf install goldendict) or in the SMPlayer application (sudo dnf install smplayer). Just open the application, then select View - Information and properties, navigate to Video codec tab. All codec names will be truncated.
