Noise on Wayland login
SUMMARY
When logging in to Plasma Wayland, the first thing to be displayed is a garbled
image of whatever was on the screen before, inverted around colors, misplaced
regions, some blocks from vram, or just noise if logging in directly after boot
without a display manager, with the mouse cursor on top, this usually stays
from a few seconds to over 10 seconds, until the desktop loads in.
STEPS TO REPRODUCE
1. Login to the Wayland session
2. Notice screen for the first few seconds
OBSERVED RESULT
Garbled/distorted framebuffer content from the display manager, or the last
boot if rebooting (without a display manger, auto login).
It is usually white blocky noise if booting up cleanly and directly to Plasma.
EXPECTED RESULT
Black screen or the desktop
