Title:
horizontal lines bottom of screen
Status in linux package in Ubuntu:
Incomplete
Bug description:
roughly 25 lines appear at bottom of display in uefi, grup, and after boot.
(1 mm apart)
When a window arrive at bottom of of the screen the lines pattern change :
they become 2 mm apart.
They do not appear in screenshot.
Using additional drivers interface I tried to change from nvidia 535
to 550 idem and also nouveau : the problem persist.
It seems the problem appeared after update of linux-firmware
