Split from #1570#comment:3. For macos, see #1794.

We currently fallback to non-opengl rendering for windows with the "has-alpha" flag.
This is generally fine since transparent windows aren't normally used for fast moving content (the type of content that benefits the most from opengl accelerated rendering).
