Description westerbly+kde 2024-03-14 22:04:21 UTC 
SUMMARY
On a KDE 6 Wayland session, I get frequent freezes (including mouse cursor) that last for about 1-5 seconds. Frequency is about 5 minutes or so, depending on what I'm doing. It seems some applications trigger the bug more often, but I consistently get them during normal usage. For example I just got one right now while typing this.


STEPS TO REPRODUCE
Use the system normally (web browsing, watching videos or gaming) in a Wayland session (possibly with an NVIDIA card) for an extended period of time.

OBSERVED RESULT
Frequent but irregular compositor freezes that take as long as 5 seconds to resolve.

EXPECTED RESULT
Smooth usage under normal conditions.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Linux 6.7.9-arch1-1 (64-bit)
KDE Plasma Version: 6.0.1
KDE Frameworks Version: 6.0.0
Qt Version: 6.0.2

ADDITIONAL INFORMATION
journalctl -ab -e shows right after the freeze:

This is consistent. I have quite a few instances of this exact log, and I spent some time monitoring so I could catch and verify that these are (pretty much) always the last messages after a freeze.

I am using an RTX3080 with the 550.54.14 proprietary drivers.
Comment 1 westerbly+kde 2024-03-29 17:55:22 UTC 
Update: after a few updates to KDE and the NVIDIA drivers, I don't get the same error messages anymore in journalctl, although the problem persists. This seems to be the message associated with the stutters now:

SOFTWARE/OS VERSIONS
Kernel: Linux 6.10.7-arch1-1 (64-bit)
KDE Plasma Version: 6.1.4 (Wayland)
KDE Frameworks Version: 6.5.0
Qt Version: 6.7.2
NVIDIA Driver: 560.35.03 (proprietary, not open modules) w/ RTX 4080

I'm seeing something similar (or the same) as this. Everything appears to be fine until apps and plasma itself suddenly start to hang or become unresponsive sporadically. Can't seem to isolate a particular cause either. This last time I was playing Just Cause 3 and the game started to repeatedly freeze for several seconds at a time and then I saw it was everything, not just the game. Other times it has happened I was doing basic things like using Firefox. IIRC, it has resolved itself once in the past when I let the system sit, but it can take a while so I just reboot at first sight now.

I'm just not sure how useful these logs are given I see these errors occasionally even when I see nothing going wrong. Would attaching a debugger to kwin until it happens again be more appropriate?

Are these warning messages printed when you have the task switcher open?
Comment 4 Martin K. Scherer 2024-11-12 15:47:00 UTC 
I can confirm that this only occurs if the task switcher renders previews of the windows. Since the messages are so excessive users with slower hardware (storage) will experience hick ups.

If I set a task switcher style which does not involve window previews, no messages pop up in the logs.

This behaviour does not seem to have changed during the versions (kwin-5.x to 6.x).

As the previews of the windows are correctly rendered,  I recommend to catch the message (exception?) and lower its verbosity to debug etc., if the hardware configuration is based on Nvidia DRM.
Comment 5 Martin K. Scherer 2024-11-12 16:48:32 UTC 
Because I just forgot, my logs are flooded with only entries of these entity during task switching:

kwin_wayland[$pid]: kwin_scene_opengl: 0x502: GL_INVALID_OPERATION error generated.

Used versions: 
kwin-6.2.3
nvidia-open-dkms-565.57.01

I'll start with the fact that I use a laptop, but it has an NVIDIA GPU and an external monitor is connected that uses said GPU, so I'm guessing my issue is related. 

I also get frequent 1-5 seconds freezes and I get nothing in the logs besides these.

Sorry for taking so long. I do not have this issue anymore.

That's great news. 

Is anyone else still seing the freezes on Plasma 6.3.2?
If so, are the log messages the same?

Thanks to your hard work this bug seems fixed!
Comment 11 TraceyC 2025-03-18 19:12:22 UTC 
Good to hear! Since at this is fixed for at least two people, I'll close this report out. If anyone is still experiencing freezing, please open a new report since the cause is likely different.
