srcv@ can you send a screenshot from this issue? I cannot access the link on #1 for some reason. I am curious if the problem is in the input canvas or output video.

It looks like the problem is in the input canvas (the upper content on the picture) and captured stream has it too as a result. Somehow the original video doesn't get drawn completely onto canvas. It might be a padding issue. junov@ can you re-propagate it?

@dcastagna: Any idea what may have changed in video to canvas draws that could be causing this?

The biggest change I'm aware of is crrev.com/1869793002. That seemed to have landed after this problem was reported though. A few related changes have landed on CrOS side a little bit earlier. Am I right assuming kitty an X86 device? srcv@, is it possible to bisect to find out when the regression happened?
