[14:58:04.937021][warning] Some image(s) have no serial number to identify the camera/lens device.
This makes it impossible to correctly group the images by device if you have used multiple identical (same model) camera devices.
The reconstruction will assume that only one device has been used, so if 2 images share the same focal length approximation they will share the same internal camera parameters.
14 image(s) are concerned.

Are you using x11 rather than Wayland? This may be related to not using Wayland. Using Budgie 24.04, I use meshroom 2023.2 to setup my pipeline and save the .mg

See #2902

[reset12]

I am using X11.

[roydenyates]

I am using X11.

Then that likely is why the UI lags so badly. I believe xubuntu now has Wayland even if beta, so try that.

Same issue here, Wayland isn't a option for many users as large distros like Mint don't fully support it yet, so pls fix that for X11
