Issue with AppSink

[Jaskarn Kalsi]

We have a pipeline that worked well on ubuntu 18 with gstreamer 1.15
We have upgraded Ubuntu to 20.04.
Now the same pipeline keeps filling up the queue before appsink if any cpu
bound process is executed.
It stops pushing frames.
to the next pipeline which is an appsrc.
callback kind of pauses, and after sometime frames start to populate again.

decklink -> videoconvert -> queue -> appsink
appsrc-> queue -> tee -> fakesink

appsink has drop set to True.
so queue behind it should not get overflowed.

Thanks & Regards,
