Bug description:
  When writing into text fields in some applications (Firefox, VS Code)
  on Jammy in a GNOME / Wayland session, I can see an effect best
  described as the glyphs appearing / disappearing sometimes repeatedly.
  I have attached a recording from my phone (since attempting to record
  a screencast fails).

  This doesn't happen always, and it appear somehow sensitive to some
  environmental condition (load?) since for example when I'm on a video
  call, the effect seems to not be happening so often.

  I have also experienced a few instances of a currently not-focused
  window disappearing (seeing through to a window that is below that
  window), but cannot reproduce that reliably.

  I have the NVIDIA driver 510 in use, RTX3090-only 16-core Zen1
  Threadripper system with no integrated GPU.

  No similar effects visible when in a GNOME / Xorg session.
