getDisplayMedia capture the view of the screens and windows
in the capture dialog, but the issue is that captured view
of the Youtube somehow is blank. It repros only in certain
circumstances, for example, Canary channel.
If user reinstall the Canary as fresh new, we observed that
it doesn't repro.
Cause:
We aren't sure what's cause of this one yet.
Solution:
We decided to provide fallback WGC capturer when the main
capturer (GDI) shows blank. WGC could show yellow outline
in prior Win11 OS, but yellow outline looks better than
blank.
The blank detector and fallback capturer are what screen capturer
already supported. So, the solution will follow similar
pattern in the window capturer.
