Public bug reported:
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.
