vah264enc/vah264dec after recent upgrade to 1.22.8 from 1.22.7
When I add ! vah264enc ! vah264dec to a pipeline I get weird scan lines on top of my expected output, eg
gst-launch-1.0 -v videotestsrc ! "video/x-raw, width=(int)1920, height=(int)1080, framerate=(fraction)60/1" ! vah264enc ! vah264dec ! queue ! xvimagesink
I noticed this after recently upgrading my system from the 1.22.7 to 1.22.8 version of the following packages:
gst-libav gst-plugins-bad gst-plugins-bad-libs gst-plugins-base gst-plugins-base-libs gst-plugins-good gst-plugin-va gstreamer gstreamer-vaapi (these are Arch packages)
I tried downgrading to the previous versions but still see the same problem now, which makes me think it may not exactly be a bug in gstreamer but in some other dependency package. I looked through my upgrade logs and through the set of libraries that gst-launch-1.0 links to using ldd $(which gst-launch-1.0) but nothing particularly stood out to me.
Here are my upgrade logs:

The larger context for my use case involves using these two plugins, vah264enc and vah264dec, in two network-separated pipelines to encode and later decode video data between two applications. (I'm also open to non-h264 alternatives anyone might have to accomplish something similar).
Thanks in advance!
