Public bug reported:
Hi,
This issue has been going on since I first installed Ubuntu. At random,
the display immediately quits updating at a reasonable rate and has
extreme lag. Best way I can explain the visual is as if the device is
memory bottlenecked and the desktop windows are severely lagged. Only
way to overcome the bug is to reboot from my current findings.
-----edit-----
I should add, 'at random' typically involved me using vscode or firefox, but no
particular action or activity I've noticed causes this. This latest event was
while watching a video, but has not been limited to video playback occurring.
---end edit---
Contrary to the visual, this is not a performance related bug. At every
recent instance of this event I verified memory(& swap), CPU, and GPU
usage and their respective performance by benchmarks. There is no impact
to the performance during the bug compared to normal usage. There are no
abnormal levels of memory/cpu/gpu usage.
This problem has occurred both after a fresh reboot, and after suspend,
so it is not sleep state bound.
During the bug I have switched to tty3, and the lag was still present,
which suggests this likely isn't a gnome/wayland/xorg bug but rather a
kernel/driver bug. The instability may have been created as a result of
being in the graphical environment, however, so it is not certainty.
Given Zenbooks have issues with poor performance after suspend (which I
found to be possibly attributed to the charger being plugged-in when
invoking suspend), I have yet to confirm if the bug occurs both on & off
the charger, but my recollection tells me it does. I mention this out of
possible relation.
I'll attach an image of graphical artifacting I've caught, which may be
related but I'm uncertain. The artifacting occurs generally while
switching program windows or scrolling on Firefox.
I'll also attach excerpts of journalctl, two of which are prior events
from this week (not full logs, but are around the timestamp of the bug
starting; possibly grepped, I can't recall), and the rest are from today
(a full dump, at event, and specific grep):
prior events files:
journal_1_aroundevent.txt
journal_2_aroundevent.txt
latest event files [event occurred ~02:07]:
journal_3_atevent.txt
[fetched with journalctl @ ~02:08 and copied from 02:07:00 onward]
journal_3_grep.txt
[fetched @ ~02:20 with journalctl -b | grep "Jul 16" | grep -E
'desktop|display|amd|amdgpu|gpu|graphic|graphics']
journal_3_fulldump.txt
[fetched with journalctl -b -1 > ...]
Hopefully what I've provided is of some assistance, but I'm fully open
to getting more information/logs or attempting fixes so long as they are
safe. I recognize Ubuntu recommends to provide a dmesg dump during bugs
like this, so that will be attached as soon as this bug happens again.
If this is a kernel bug and there is a better place to report this to,
please let me know.
