Image artifact on the monitor

ozooha · 2021-04-20 23:39:18

I am attaching a video of the issue as I wasn't sure an image would capture the same.
video link
The artifact is on the left of the category letter on top of the video. It is a shimmering bunch of pixels bunched as vertical lines.
I have noticed that it occurs for the colors which are around the "red" region of the RGB spectrum.
My graphics card is - GPU: AMD ATI Radeon 540/540X/550/550X / RX 540X/550/550X and it uses the amdgpu open source driver.
How do I fix that, if ever it is related to the graphics driver?
Let me know if you require any other information.
Thanks for your time and attention.

https://bbs.archlinux.org/viewtopic.php … 9#p1967109 - seems a mesa regression.

Otherwise see https://wiki.archlinux.org/index.php/AM … cy_problem
Basically try passing

amdgpu.dc=0 amdgpu.audio=0 amdgpu.dpm=0 amdgpu.aspm=0 amdgpu.runpm=0 amdgpu.bapm=0

to the kernel and see whether that fixes anything, then narrow down to the crucial parameter.

Last but not least, in case this is an external display: #1 of all weird stuff is still the cables ;-)

So nothing worked here and yesterday had a recent mesa update.

Did you try to mesa-git as suggested in the linked thread?
Do the artifacts show up on screenshots?
What's the output of "xrandr -q"? Do they also show on lower resolutions?

ozooha · 2021-04-23 23:11:02

Yes I tried the mesa-git as well and the issue did not go away.

Its the HDMI one which has the issue not the Display port.
I hope this helps.

quelle surprise…

So let's try to make it really easy for the system.

xrandr --output DisplayPort-0 --off
xrandr --output HDMI-A-0 --mode 1024x768 --rate 60.00

Still artifacts? If not, to they re-appear when activating the DP output

xrandr --output DisplayPort-0 --auto

Yes the artifacts don't go away despite making your suggested changes.
Also just updated it to the most current mesa version which showed up as an update.

No, I meant when you make a screenshot (eg. using scrot) are the artifacts on that screenshot (*not* on a recording of your display).

ozooha · 2021-04-25 00:03:11

No the screenshot doesn't give me the artifact since I viewed them on both my displays.
The issue appears on the HDMI whereas it doesn't on the DisplayPort.

seth · 2021-04-25 07:03:40

Can you attach the hdmi output to a different system?
Does it happen w/ a completely different software stack (some live distro)?

I tried with a new live distro and it happens for the HDMI output.

seth · 2021-04-25 19:55:47

Try an old one (or at least an old kernel, eg. grml, maybe a release from 2019) but this increasingly means output, cable or panel (hardware).

From the edited post I assume you already tried a different cable?
Does the HDMI monitor have other inputs (eg. VGA) that you could test?
Are there any adapters involved and if not, can you use the DPI out w/ an adapter to feed the HDMI monitor?

I will try this out and get back to you - it might take longer unless I use downgrade to install an old one....any suggestions for trying this out quickly?

seth wrote:

Correct I have tried this option with no success.

seth wrote:

It has a VGA, however I use the Graphics card which does not have one. It has, as mentioned, DisplayPort and HDMI.

seth wrote:

The DisplayPort end uses an adapter which is is a DisplayPort-to-HDMI. I could try this I suppose.
Will revert back when I test this part which should be easy.

Thanks,

https://mirror.ungleich.ch/mirror/grml// - this isn't related to your arch installation and you don't have to downgrade that to get to an older grml image.

This did not work I tried all the permutations.

Pardon my ignorance.
Should I be using one of the 2019's version of this Distro's iso as a live Distro?
Thanks,
OZooHA

ozooha · 2021-04-25 22:40:40

So I ran the grml as a live distro and still those artifacts are visible.
Please see the image. It manifests as a red arc on the right against the sky starting from the building top.

Thanks,
OZooHA

So it's the hardware, it's not the cable, I understand you tried attaching it to the displayport output with the adapter/cable that works fine w/ the outher monitor?
At this point you can try whether the VGA input shows the same problem (on some system w/ a VGA output, obvously) and get used to the idea that it's the panel itself :-(

ozooha · 2021-04-26 23:07:54

I did a factory reset to the monitor and things diminished a lot.
Today after the linux-firmware upgrade seems to have made that issue disappear.
This appearance and disappearance of the issue seems to have happened twice and likely due to package installation.
I am not sure whats happening, frankly.

Thanks for your help. Much appreciated. I guess I have to live with it and also this is a 13 year old monitor (brand name - HANNSPREE).
