KDE sometimes unresponsive

I am having some problems which I find difficult to explain.. Basically after logging in the DE environment sometimes (not always) becomes unresponsive. And sometimes there is a delay at the login screen (SDDM).  I thought I had solved that by configuring SDDM to use Wayland, but after a while the problem returned. I am uncertain if the problem is a result of an update or from a powercut I had around the same time.

Kernel 6.11.9
Plasma/KDE 6.2.3/6.8.0

Symptoms:
1) At the login screen (SDDM), sometimes a delay upto 20 seconds before keyboard/mouse becomes active.
2) After login, splash screen sometimes takes about 5 seconds.
3) Sometimes no panels or icons, just wallpaper background. No keyboard shortcuts work (including ctrl-alt-F2/3/4/etc)
4) Sometimes all icons are bunched together on the taskbar (overlapping) and inaccessible, as is the app-menu. keyboard works and programs can be launched using terminal.
5) Sometimes app-menu is inaccessible, but icons are displayed, but then clicking them just shows the cursor loading and then stopping again without launching the program. Keyboard doesn't seem to work (no terminal/TTY).

Most of the times I need to reboot using the powerbutton and after awhile I get a boot that works.

Something else I noticed is that at times I loose internet-connection, then disconnecting and reconnecting seems to work. I mention it because this problem started around the same time and I see some network related entries in my log.

The log is here: https://pastebin.com/NEuUqNTh. If other logs or info is required, please ask. I would be very grateful is someone can help me figure this out (I do not want to do a clean install atm)

Re: KDE sometimes unresponsive

There's a bunch of crashes related to bluetooth access in the kernel at the end of that log. Do you use BT mice/keyboards? Reads like a broken mediatek wifi/BT driver, they started to have a bunch of issues in the 6.11 kernels, see e.g.: https://bbs.archlinux.org/viewtopic.php?id=300335 -- does downgrading the kernel a version help?

Re: KDE sometimes unresponsive

I only have a Wacom tablet that I very seldom use which is connected to BT. I can use it wired as well, so I might just disable BT to see if that helps. Also, I believe 6.12 is (about to be) released? I'll look if either/both of those solutions work. If not I'll try a downgrade, if only to help track down the problem.

Re: KDE sometimes unresponsive

yeah 6.12.1 moved to stable so you can test that as well.
