nvcompositor not accepting NVMM memory type

Dear all,
I came across a rather annoying “feature”, i.e. it seems that in GStreamer, the Nvidia plugin nvcompositor does not accept buffers in NVMM memory type.
The following works:

gst-launch-1.0 \
nvcompositor name=mix sink_0::xpos=0 sink_0::ypos=0 sink_1::xpos=0 sink_1::ypos=240 ! nvoverlaysink \
videotestsrc ! mix.sink_0 \
videotestsrc ! mix.sink_1

But this does NOT:

gst-launch-1.0 \
nvcompositor name=mix sink_0::xpos=0 sink_0::ypos=0 sink_1::xpos=0 sink_1::ypos=240 ! nvoverlaysink \
videotestsrc ! nvvidconv ! mix.sink_0 \
videotestsrc ! nvvidconv ! mix.sink_1

Since gst-inspect-1.0 nvcompositor gives:

Pad Templates:
  SINK template: 'sink_%u'
    Availability: On request
    Capabilities:
      video/x-raw(memory:NVMM)
                 format: { (string)RGBA, (string)I420, (string)NV12 }
                  width: [ 1, 2147483647 ]
                 height: [ 1, 2147483647 ]
              framerate: [ 0/1, 2147483647/1 ]
      video/x-raw
                 format: { (string)RGBA, (string)I420, (string)NV12 }
                  width: [ 1, 2147483647 ]
                 height: [ 1, 2147483647 ]
              framerate: [ 0/1, 2147483647/1 ]

This is a clear bug, please fix :)

Hi,
We should fix it in r32.2.1 and afterwards. Do you run an older version?

This is version 1.8.3 of nvcompositor of the jetpack 4.2

Please upgrade the system to r32.2.1 or r32.2.3 through sdkmanager.

I can confirm that it works on the latest version.
