Just the panel on the external screen? Or does it also affect all of Plasma (i.e. also the panel on the main screen and also the desktop)?

Please attach kwin's and plasmashell's logs. Run the following commands in terminal

  journalctl --boot --user-unit plasma-kwin_wayland > kwin_wayland.log 2>&1
  journalctl --boot --user-unit plasma-plasmashell > plasmashell.log 2>&1

and then attach kwin_wayland.log and plasmashell.log to this bug report. What GPU do you have? If you disable VRR in system settings, does it make any difference?

I have a RX 6700 10GB and disabling vrr doesn't solve the problem

This is reported against 6.3.91. Is it a regression or pre-existing issue in 6.3?

sorry this is a per-existing issue after testing 6.3.5 on a different distro
