Stutter every 10 seconds on video playback

If this is the wrong place to report this, I’d be incredibly grateful if someone would let me know where to report it.

A similar, or possible identical, issue was previously reported by another person at: Video playback issues

With VLC or on web browser, after a day or so of uptime video playback has a very brief stutter every 10 seconds of play. When playing the same video it isn’t consistent at what timepoints the stutter occurs, but the 10 seconds between stutters is consistent. This is video only; the audio continues uninterrupted. And the audio and video feeds resync after the stutter.

By “stutter” I mean the video stream pauses on a single frame very briefly and then jumps to the appropriate frame that is synced with the audio. This pause is on the order of a fraction of a second.

I have seen this on both X11 and Wayland. This particular issue does not occur on the budgie window manager (X11), so that seems to indicate this is Gnome specific.

Ubuntu 24.04.02 LTS
Lenovo G780
Intel® Core™ i7-3520M
Intel® HD Graphics 4000 (IVB GT2)
16 GB RAM
Gnome 46
Linux 6.8.0-71-generic

I don’t know what other information might help isolate this issue. I lack the technical knowledge to troubleshoot any further, but am happy to run any apparently safe and sane shell commands to gather further information.

Okay, I’m now noticing that this does not appear to be solely a video player issue. It is affecting the entire video output (as seen with cursors halting during movement and then jumping).

System monitor isn’t showing any particular I/O wait or CPU overhead, and the core temperature is fine. free shows plenty of available memory, and only slight (<1 GB) use of swap.

I am using a D-Sub monitor connection. I’ll hook it up to an HDMI adapter, instead of direct, and see if that changes anything after the next reboot.
