After upgrading from 35.2.1 to 35.3.1, the running interface of the software is stuck

Autonomous Machines Jetson & Embedded Systems Jetson Orin NX

We use the ORIN NX module. With version 35.2.1, our software works as shown below.

But with version 35.3.1, the software stalls abnormally, as shown in the video below

We compare these two versions of the presentation, and it looks like the underlying software version is the same.

We use the same set of hardware equipment, as well as the same set of software source code, but the L4T version is different, for testing.

How can I troubleshooting the problem? From the running situation of the program, the click switch function has finished running, but the interface refresh has some problems.

Hi,

Could you describe more details about the interface issue?
Do you mean something issue related to the UI?

Thanks.

Sorry for the late recovery, our program uses QT to do the UI interface. The UI refresh of version 35.2.1 is normal. Since the 35.3.1 UI refresh has been delayed, we’ve ensured that the QT version is consistent. Include other libraries with consistent versions.

Hi,

Could you share a reproducible source with us so we can check it further?
Please also help us to collect the status of the GPU usage for both cases.

$ sudo tegrastats

Thanks.

We found this problem when using QT’s OpenGL library to call GPU rendering. Do you have any good suggestions?

7

Hi,

It looks like the UI is blocked as the GPU resources are occupied.
Could you monitor the device to see if the GPU is fully utilized?

$ sudo tegrastats

Thanks.

Hi,

From your tegrastats log:

The VIC frequency of the r35.3.1 environment is much higher (729 vs. 115)
Is there any app using VPI VIC hardware in the background?

Thanks.

10

Could you please provide commands or tell me how to query apps using VPI hardware? We just deployed the same software program at present.

11

Hi,

Sorry that it is a typo.
It should be VIC instead of VPI.

VIC (Video Image Compositor ) is used for 2D image and video operations.
Like UI scaling, blending and rotation operations, and video post-processing.

Is there any related app running at the same time?
If not, could you share a reproducible source/steps so we can test it in our environment?

Thanks.

12

testOpenglApp.tar.gz (25.6 MB)
Execute the qttest1 file in the testOpenglApp directory.

qttest1.tar.gz (1.0 MB)
Here is the sample source package.

13

Hi,

Thanks for sharing the source.
To help us test this quickly, could you also share the command of setup and execute the qt app?

Thanks.

14

We use qtcreator to compile it.

At the same time, you can directly run the binary file to see the phenomenon.

15

Hi,

Would you mind sharing the commands/steps to reproduce this issue directly?
This will help us to give it a try quickly.

Thanks.

16

The steps of reproducing a phenomenon.

sudo apt-get install qtcreator -y
tar -xf testOpenglApp.tar.gz && cd testOpenglApp/
./qttest1

And then，As shown in the video，Use the mouse to repeatedly click the Normal Page and Opengl Widget buttons in the upper-left corner of the interface.
After a single click, the screen changes slowly without moving the mouse or keyboard.

17

Select the switch interface by tab switch + space. When switching back to the normal interface, do not move the mouse, or no longer press the tab key, and the screen will not switch

18

Thanks, will give it a try and update more info to you.
