Summary:

These are the results from testing tinderbox build from 3/6/2012

The biggest offending bug is bug 732564: maple Get viewport handling good again. It's possible that a few bugs being fixed may cause maple to be better.

• Blurriness (on land or changing tabs) can be an issue in terms of readability ( bug 729615)
• Software Keyboard is not usable due to bug 732564 in Maple
• Checkerboarding from going back and forth on applications (bug 732563).
• Performance so far has been less than 30 fps on most websites.(bug 729082)

QA would not sign off until there are certain bugs fixed.

This shows all the blocking bugs: https://bugzilla.mozilla.org/showdependencytree.cgi?id=725095&hide_resolved=1 Other Bugs/Issues:

• bug 732119 - MAPLE: parts of background never drawn on graph server
• bug 727142 - MAPLE: 2.1 devices crashes on startup

• Naoki - I ran into some crashers which are hard to reproduce. I believe they might be OOM issues though.

On the Good side:

• Maple has fixed some issues with jankiness on panning esp in landscape.

Would you sign off on maple?

• Aaron - Not until it meets the level of quality on par with Nightly
• Naoki - Not until viewport and blurry bugs are fixed
• Tony - not until that blurry bug is fixed. bug 729615
  • bug 732564 happens pretty often for me once i click on a new page. It minimizes the viewport and leaves an empty blank window
  • also, what is the expected FPS that devs are targeting before merging? 50? 60 FPS? no specific number
• Martijn -
• Kevin - Viewport bug 732564
