[pipewiresrc] UI starving for resources?

Hi there…
I have a very weird issue using GStreamer under Ubuntu 24 (GNOME Wayland) on an NVIDIA RTX4090.

This pipeline
pipewiresrc fd={1} path={2} ! videorate ! videoscale ! videoconvert

creates a very intense stutter on my JavaFX program and makes its user interface choppy, in addition there is some black artefact on the UI as you can see on this video:

sometimes the UI renders a black frame before returning to a normal image.

This pipeline does not create this error:
pipewiresrc fd={1} path={2} ! videorate ! cudaupload ! cudascale ! cudaconvert ! cudadownload

It’s like if the pipeline makes the program to starve for resources…

Any idea on how to solve this?

ok I solved by upgrading NVIDIA drivers to version 555.
