Well, looks like bug occured again.
In drm-tip, and also it occured in version v5.19.5
I realized, that I have also computer with se same(i believe) graphic
card, and i do not remember for problem to occur on this pc even once.
so I looked for difference in these two computers.
I tried these commands to find difference:
glxinfo -B
lscpu
lshw
And (from my point of view) interesting difference is:
glxinfo:
Pc where error does not occures:
Version: 22.0.1
Video memory: 3072MB
pc where error occures:
Version: 22.0.5
Video memory: 15928MB
(note, that pc where error does not occures has 8GB ram, and the one where
error occures has total 16GB ram.) ie, probably video memory can consume entire
ram?
But I did not remember setting that, so these have to be default settings, or
do not know.)
lshw:
pc ok: lshw
product: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz
vendor: Intel Corp.
physical id: 1
bus info: cpu@0
version: 6.78.3
size: 2800MHz
width: 64 bits
pc nok: lshw
product: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz
vendor: Intel Corp.
physical id: 1
bus info: cpu@0
version: 6.78.3
size: 2700MHz
capacity: 2800MHz
width: 64 bits
there is different "size" value, and pc that does not shows screen
shifting misses "capacity".
lscpu differs in these two rows:
pc ok: lscpu
Vulnerability Spec store bypass: Mitigation; Speculative Store Bypass disabled
via prctl and seccomp
Vulnerability Spectre v1: Mitigation; usercopy/swapgs barriers and
__user pointer sanitization
Vulnerability Spectre v2: Mitigation; IBRS, IBPB conditional, RSB filling
pc nok: lscpu
Vulnerability Spec store bypass: Mitigation; Speculative Store Bypass disabled
via prctl
Vulnerability Spectre v1: Mitigation; usercopy/swapgs barriers and
__user pointer sanitization
Vulnerability Spectre v2: Mitigation; IBRS, IBPB conditional, RSB
filling, PBRSB-eIBRS Not affected
Main difference is in seccomp, and PBRSB-eIRBS Not affected... have no
idea if it is something interesting.
anyway, full list of response commands is in attachment.
I may try to downgrade from version 22.0.5 to 22.0.1 but i am not sure
what exactly to downgrade.

Title:
[i915] Ubuntu display get shifted after some time.
Status in linux package in Ubuntu:
Incomplete
Bug description:
It is continuation of this bug:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1986583
where advised fix was applied.
Summay: After ubuntu is turned on, after some time screen gets shifted
to side. (and starts to overlap)
I setup webcamera to record screen, and video below shows what it looked
like.
after fix were applied.
www.ms.mff.cuni.cz/~krasicei/capture-0231.bug.crop.slow.mp4
(video was cropped, and slowed down 2x)
before fix was applied shift looked somehow like this:
www.ms.mff.cuni.cz/~krasicei/bug17-50-18-8-2022.c.mp4
(video is also cropped, and slowed down 2x)
During shift no one was present on computer.
Is there any idea how to enable some more detailed log or something? I
probably can pinpoint exact moment in time when shift happened.
i tried to read log journalctl, but I found nothing interesting.
