Pixels from one stream leak to another

I have two streams: one horizontal 1280x720 video and another is vertical 720x1280. The whole pipeline is set for 1280x720 so the vertical stream is downscaled. Sometimes when processing both of the streams, after some time I witness a bug when pixels from a horizontal video leak to the borders of the vertical. In normal cases frames of the vertical video have only black pixels at left/right sides. It looks as if the surfaces are not cleared and reused somewhere inside. Is there such known bug? Did I do something wrong? Thanks!

Still important

What’s your pipeline? How do these two streams display on the screen? Could you share a picture about this issue?

There is no update from you for a period, assuming this is not an issue any more.
