I created legacy/trac#27348 (moved) for the onboarding issues. Let's keep this ticket for the about:tor UI bugs. The branding issue applies to more than just about:tor, but it already has its own ticket: legacy/trac#18058 (moved).

Summary: TB8.0a10 UI Bugs to TB8.0a10 about:tor UI Bugs

Here is a patch that address some of the about:tor issues: https://gitweb.torproject.org/user/brade/torbutton.git/commit/?h=bug27301-01&id=3bf17f3f9ca7fd40ed13d40f628384d38ba71368

It turns out that we cannot use higher resolution PNGs at this time because of legacy/trac#27357 (moved). We should fix that ticket or legacy/trac#27002 (moved) soon.

Also, the onion circles located near the bottom of the page are not added dynamically; we just have a fixed number of them. Previously there were 14 in each row; now we have 20 in the top row and 21 in the bottom row. This should make it much less likely that users will see onion-less space on the sides of the page (it will still happen if they have a very large display).
