nvpmodel Max-N image scratch issue

You must use a Chrome browser.

If you currently use nvpmodel Max-N and Max-P Core-All, the image will be corrupted as shown below.

There seems to be a problem with the use of six cores.

Using only four cores will degrade performance.

I want to know how I can not break an image using six cores.


Hi shyoon, are you on r28.1?
Please share clear steps so that we can reproduce the issue. Thanks.

nvidia@tegra-ubuntu:~$ cat /etc/nv_tegra_release

R28 (release), REVISION: 1.0, GCID: 9379712, BOARD: t186ref, EABI: aarch64, DATE: Thu Jul 20 07:59:31 UTC 2017


1920 * 1080 It appears when you frequently open a wallpaper with the same URL and refresh it.

Two TX2s are reproduced.

Hi shyoon,
So you run in ‘sudo nvpmodel -m 0’ and keep refreshing a URL in Chrome browser? What is the URL you open?

I was often reproduced when I opened and tested the computer desktop image as a URL.

However, any symptom appears in any image.

Small images in the original image, such as linked images, are displayed in an overlapped form at the bottom left.


I want to know how to take action as soon as possible.

Hi shyoon, we are trying to reproduce the issue.

Hi shyoon,

I can’t see overlapped issue on TX2/r28.1
My steps:

sudo nvpmodel -m 0
Open Chromium browser
Open jpeg file --> No issue.

Are you repro overlapped issue with every jpeg file? or only special jpeg file?

The link is the video I tested.

I am confident that the same test will be reproduced.

Try searching the portal site image.



Hi shyoon,

Could you list your Chromium version?


version : 63.0.3239.84

Help me. Thanks!

Hi shyoon,

My test Chromium version is 53.0.2785.143
Recommend you to use old version first, we’ll also check the newest version.


I tried, but I could not install the previous version.

Have you found the same thing with the latest version?

Hi shyoon,
Please check if this link helps https://askubuntu.com/questions/485856/how-do-i-downgrade-google-chrome

r28.1 is out with 53.0.2785.143. We suggest you use this revision.

I have reinstalled R28.1.

In chrome version 53, the image is not broken.

It seems to be a problem with the latest version of chromium.

Thank you.

Do you have a chrome version 53.0.2785.143 download URL?

I need…


We don’t know about it. Please other forum users can share information about this.

I’ve temporarily downgraded to Chrome version 53.

When is the stable version of Chrome with the upgraded version available?


Hi shyoon,
We will check. A BSP release is fully tested/verified with certain revision of all applications. We suggest you run default revision of Chrome on r28.1.

So what is the feature you need on Chrome 63 that you are not able to stay on Chrome 53?
