Thanks for reporting this, folks. Unfortunately I don’t have access to this hardware due to the pandemic but I filed internal bug number 3234400 to track the investigation. While the bug tracker is not public, you can use this number in future correspondence to refer to this issue.
@aplattner
Do you have any news concerning this bug?
I would like, if possible, to contribute to find the issue and maybe a solution for the quite annoying bug.
Thanks!
The bug is being investigated but I don’t have any additional information to report, sorry.

All right, thanks for the feedback.
In case there are any news, would you mind to let us know?
Thanks!
I`d just like to append to previous discussions. Im having this issue across all distros. Tried a plethora of different drivers. Any status internally?
Regards.
Nice to see that I wasn’t the only one with this issue ! Due to home office I also have not had access to the monitor which caused the problem. I’ll try to generate a report as requested when possible.

nvidia bug no: 3234400
I can confirm this issue using the lenovo dock2 (usbc , 230W) , Thinkpad p53, 2x 4K monitors@60hz via displayport. P53 firmware = 0.1.28
Driver Version: 450.102.04
software base is kubuntu 20.04.2 LTS
It would be nice if nvidia would look at this , as this is a Quadro card which we are using for business.

I will say one consistent way to trigger the bug is to scroll a large amount of text in a konsole (kde’s text console) window.
depending on the pages displayed the corruption changes size. Clearly some buffer is getting overwritten, but whose in control…;-)
updated to new driver release 460.56 but issue still persists.
any news about a solution?

Hate to be a nuisance but since we have no way of checking the status of this issue I’m curious if there’s any update. It’s somewhat frustrating to have what is supposed to be a professional level card and have these issues.

I think I have found a/the bug, that would cause overwrites, I’m not sure if it is relevant.
In my Nvidia X Server settings the dimensions are 7679x2160, but the monitors are 3840x2160!!!
We’re one pixel off…
see my post below - it looks like the monitor setup is off by one pixel, and hence with 3 bytes/pixel it paints all over the wrong bit of the screen. If it were one pixel larger, I guess it would crash more often.
I have no idea how to fix this though.
updated to new driver release 460.67 but issue still persists.
@aplattner any news about a solution?
can you show the dimensions like I did? That one pixel suggests a buffer is the wrong size…
@philathome
sure, find it attached.
The dimensions are: 7680 x 2160
But as you can see, the issue still appears. So looks like the missing pixel you are experiencing is not the cause for the issue we are facing ;)
I’ll still put my money on an incorrect buffer, especially as it is quarantined(!) to the screen on the right.
I have a refinement of the problem, I’m using KDE plasma and the terminal emulators KONSOLE.
I noticed that the corruption appears when I had a large amount of scrolling content from a process, but disappear when I switched tabs to another konsole. Does anyone know if the scrolling content is an OpenGL process?
It would seem that for scrolling performance the pixels would be stored somewhere, and it suggests a buffer overrun to become visible.
Updated to new driver release 465.24.02 but issue still persists.
in addition the external monitor is not recognized on the USB Type C Display Port anymore.
So the only option left is using the Dock, since with the dock the external monitor is at least recognized. Oh, wait a second, I can not use the dock, because the issue with static noise still persists…
Sorry to say, but this is ridiculous.
The Nvidia T2000 graphics card is not just some cheap card that can be found in every cheap consumer device. We are talking about a professional card used in High-End business workstation notebooks.
@ Nvidia driver developers:
Is there anyone working on this issue or is it just being ignored?
@aplattner does not reply or maybe even ignore this severe issue
This issue is persists since 8 Months and no news about what’s the issue or when there will be a solution for the problem.
Same issue with Lenovo Legion 5 laptop with geforce 1650Ti mobile (Ubuntu 21.04 beta plus Nvidia 460.67 drivers):
- above laptop + HP G2 Thunderbolt dock + 4K 60Hz monitor and
- same laptop + HP USB-C dock G5 + 2560x1600 60Hz monitor (happens less frequently).
Problem only appears on DP output of the dock.
What I noticed is that Digital Vibrance in nvidia-settings of the monitor affect this behavior, i.e. when this setting is turned down to -350/-400, distortions almost never happen. Also, when Color Range setting is set to Reduced, the problem seems to be gone, or at least substantially improved. Obviously, the color reproduction of the screen is much worse. The whole issue is really annoying. Hope this helps.
@tabuvudu
I checked and yes, when reducing the Digital Vibrance to the minimum (-1000), the issue is almost gone - but than have only Black & White Screen. Welcome to the 70s
The Color Range setting effects the issue only slightly.
What is now even more annoying: with the 465.24.02 drivers, the USB Type C DisplayPort is not recognized anymore.
anyone else having this issue?
@aplattner - could you please participate to this discussion?
It is really frustrating sitting in the homehoffice being unable to use an external monitor!
