In Safari 8 on Mac OS 10.10, the "Create a game" popover appears partly off-screen:

The “Play with a friend“ and ”Play with the machine“ boxes both appear off-centre too:

As far as I know, thibault's primarily targeting Chrome, and doesn't bother with Safari much.
I'm curious, how does it fare since the recent update to the chessboards? I'm wondering if Chessground runs better in Safari than chessboard.js does.
I've seen a few glitches (sound out of sync with movement by about 0.5 seconds, pieces suddenly scaling during replay of games, animation doesn't feel quite as smooth as in Chrome), so I've gone back to Chrome for now.
The new Safari is great, though, especially the tab management and minimal header area – it's my default browser now. I just use Chrome for lichess!
