It looks like the chaperone visual is lagging behind.  I tried to capture a video of the effect, recorded from the SteamVR mirror display, but the lag doesn't show up in the mirror display.~~"},"comment":{"url":"https://api.github.com/repos/toji/chrome-webvr-issues/issues/comments/255518374","html_url":"https://github.com/toji/chrome-webvr-issues/issues/73#issuecomment-255518374","issue_url":"https://api.github.com/repos/toji/chrome-webvr-issues/issues/73","id":255518374,"user":{"login":"ollyhayes","id":6783708,"avatar_url":"https://avatars.githubusercontent.com/u/6783708?v=3","gravatar_id":"","url":"https://api.github.com/users/ollyhayes","html_url":"https://github.com/ollyhayes","followers_url":"https://api.github.com/users/ollyhayes/followers","following_url":"https://api.github.com/users/ollyhayes/following{/other_user}","gists_url":"https://api.github.com/users/ollyhayes/gists{/gist_id}","starred_url":"https://api.github.com/users/ollyhayes/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ollyhayes/subscriptions","organizations_url":"https://api.github.com/users/ollyhayes/orgs","repos_url":"https://api.github.com/users/ollyhayes/repos","events_url":"https://api.github.com/users/ollyhayes/events{/privacy}","received_events_url":"https://api.github.com/users/ollyhayes/received_events","type":"User","site_admin":false},"created_at":"2016-10-22T09:44:21Z","updated_at":"2016-10-22T09:44:21Z","body":"I'm also seeing this latency in Chromium.\r\n\r\nYou can view it in this page: https://olly.fr.to/vr.html. Position the box into the corner of the chaperone with the arrow keys and then just stand on the other side of the room. In Chromium you only need to wiggle your head very slightly to get the box to jump to either side of the Chaperone, where as in Firefox it looks completely fixed.\r\n\r\nLike jzitelli says in his first comment, when viewing this in the headset mirror the box and the chaperone move as one.\r\n\r\nIs this affecting all vive/chromium users or is it dependent on card/drivers etc?"}}
