requestAnimationFrame passes wrong timeStamp in latest Chromium build #126

Closed customlogic closed 7 years ago

customlogic commented 7 years ago

The VR display's "requestAnimationFrame" function should pass a parameter to the callback that represents the current time (docs). However, in the latest Chromium ( Oct 29 build) with an HTC Vive i'm seeing a bogus time being sent. The time starts at -92 seconds and counts up to 0 then continues on as normal. This problem didn't exist in previous builds (Sept 23, etc).

I've created a quick example to show what's going on: https://jsfiddle.net/zs4j5s3j/4/

If you open this in regular chrome, or previous builds, you'll see the current time reported correctly. In the Oct 29 build, you'll see the negative time I'm talking about: chromium_bug

Actually, I believe this is resolved in the early Feb 2017 build...

I can confirm that the time in the example (https://jsfiddle.net/zs4j5s3j/4/) is positive again in the Chrome Feb 17th build.

I checked as well, and it does appear to be fixed. Thank you!
