I don't think that we have encountered the issue with a changing eglSurface yet, so I \
expect we will need to change some of the plumbing to let that work right. I think \
that it would make sense to make the change for a general case - even if we have not \
encountered the need for general Linux yet.

Would you file a Jira?

I would be happy to work through the issue with you.
