JavaFX UI unresponsive when screen capturing on Linux Wayland

Hi there...
I have a very weird issue using GStreamer under Ubuntu 24 (GNOME
Wayland) on an NVIDIA RTX4090 and JavaFX.
This GStreamer pipeline captures the screen on wayland.
`pipewiresrc fd={1} path={2} ! videorate ! videoscale ! videoconvert`
and it 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 state.
JavaFX UI seems a bit unresponsive in Wayland, even when not using
GStreamer.
There is no issue on X11.
Using JavaFX 23.
Any idea on how to solve/workaround this?
Thanks!
