6.2.3 Monitor screen freeze when playing Video

Help
1

Since the 6.2.3 update I now had several times one of my Monitor completely freeze when playing a Youtube Video in my browser (Firefox).
Most times full screen but it even happened once just playing in the window and while most times at the same (second) Monitor at least one time it happened with the third.
Sound continues but I can not move my Mousepointer on that screen or interact with it any other way. Even killing Firefox does not help to Unfreeze.
What works is to log out that unfreezes the Monitor and after relogin everything works again like nothing ever happened.

Just took a look at the log for yesterdays incident and all I got in that one to two minutes time frame until realizing that it is not just a still image shown but frozen is:

kwin_wayland_drm: Pageflip timed out! This is a kernel bug

18 times, nothing else.

Google found a relatively recent KDE bugtracker entry about that, but they talk about that it is in the AMD driver part of the Kernel (and fixed now).

Well, I do not have anything AMD or use that driver.
Around the same time when 6.2.3 came out I got a update to Nvidia 565.57.01 as well and while /usr/bin/kwin_wayland runs with 2MiB used on that driver (according to nvidia-smi) I do not prime-run my browser, the intel iGPU with its i915 driver should be in use for that video.
Kernel got probably updated at least twice or trice since.

Anyone any clue?

Little bit more “plasmashell” error output in the Log today:

Just in case you hadn’t already seen it, there’s also an Arch Linux Forums thread on what might be a related topic if even the presence of an Nvidia card is making a difference: NVIDIA Wayland KDE Plasma Monitor Freeze / Newbie Corner / Arch Linux Forums

On the other hand, there are also quite a few issues reported around the i915 drivers:

Seemingly all from folks running Arch, the first one of those (10395) with some workaround suggestions - hopefully one of those might help in your case?

I’ve been seeing the same for 6.2.2 and 6.2.3 for about a month. I’m running Bazzite with Nvidia drivers (565.57.01).

Journalctl shows the same error message when the freeze happens. Toggling the TTY back and forth seems to work around the issue temporarily. I’ve also noticed that when I’m connected to a second machine with Barrier/Input-Leap that the second machine continues to get input and that it no longer perceives any resolution size on the KDE host machine to move the cursor too, effectively locking it to the client.

I’ve noticed this happen while streaming music in electron flatpak apps (Tidal)

As a little follow up slash rant:

With 6.2.4 and Kernel 6.12 (and whatever got a update as well) it is now, from almost daily, down to approximately once a week but still happening.

And I wonder if I just should wait and hope that it magically vanishes with the following updates?

How to even approach and find the culprit of a bug that is, even for me, impossible to reliably reproduce (as in reliably/directly to trigger)
I mean steps to reproduce:
Watch YT video and do nothing else, if nothing happens (even after hours of playtime), watch next and so on and on, and maybe or maybe not you stumble upon it. I mean, who in the right mind would do this?
