V4l2src framerate issue

I use Deepstream v.5, Jetson Xavier NX.

I made a pipeline myself.
In order to achieve the purpose of the project, we received 3 v4l2src as inputs, branched using Tee, and fused the input images and used them as inputs to the Compositor.
The tiler could not customize the position of the video, so I used nvcompositor.

But there is a strange phenomenon
I am receiving 3 inputs of 1920x1080. When the frame rate is increased to 30 or more, there are phenomena such as irregular movement of the images at each position of the compositor or exchange of the image positions in the compositor.
Changing the frame rate to 20 does not have this problem.

Can you see what’s wrong with it?

Please share your pipeline for reference. Since nvcompositor plugin does not work in DeepStream SDK, not sure how you construct the pipeline.

And please share your release version( $ head -1 /etc/nv_tegra_release )
