weird screen tearing efter booting

cvcarloscv · Today 02:41:19

i have no idea how to debug this. its been happening for a couple weeks now, hoped it would fix itself with updated but it didnt. here's a recording of the problem (had to record from my phone because the issue can't be seen in a screen recording)

i use xfce4 with xfwm4 and its default compositor, but i tried disabling compositing and also tried a xfce wayland session (with labwc) and it still happened. weirdly enough it still happens even when booting the OS (in the plymouth splash) and the ly display manager. what could this be?

Hardware issue? Less likely GPU firmware.
What hardware is this? Can you connect another monitor and check if the issue reproduces?

what nvidia cpu/gpu do you have

lspci -k -d ::03xx | nc termbin.com 9999

please post your journal

sudo journalctl -b | nc termbin.com 9999

for the previous (-1) one.

 sudo journalctl -b -1 | nc termbin.com 9999

Looks like a PSR related issue - buffer age seems unlikely because of "plymouth" and it's certainly NOT "tearing" by it's actual meaning - there's a still frame that seems to drop out for a refresh.

PSA: when recording your monitor use or makeshift a tripod (wedge the phone between two books) - or get a gimble

lscpi output (you may check the image above for info too)
journalctl output
journalctl -1 output
(termbin is so cool, didn't know this utility existed!!!)
