SUMMARY
In Electron apps, all of them running in XWayland in a wayland plasma 6
session, with an nvidia GPU, keyboard input is very laggy. I don't know if it's
input processing or painting or refresh.
STEPS TO REPRODUCE
- On Arch Linux, install Discord or Slack with system electron (which is
electron 25 at the time of writing), and type. Input will be very laggy.
OBSERVED RESULT
Laggy keyboard input.
EXPECTED RESULT
Normal keyboard input performance. Native wayland applications like Konsole are
not affected.
