** Reproduced the regression intermittently by using the Talos tp4.manifest file. Not sure what the best way to proceed.
* GL Layers on Android (ajuma, benwa)
** Working on getting talos numbers for turning on the feature. No change seen when landing this on however the feature was correctly turned on.
** Working on a user space profiler. So far we seem to be getting accurate numbers. Ehsan is adding a GUI and further instrumentation is required.
** Black flash on orientation change and resume. Should also fix crashes. Let us know if you're seeing crashes.
* heeen's update for GL layers on mobile
** Working on scrolling
*** Awesomebar, history much faster
*** Performance problem with scrollbox with the batch size attribute
*** Glitches with the URL bar. Layer conflict problem?
*** Out-of-place URL bar on Maemo, similar to problem we had with Android.
* Testday last Friday, August 26 (joe)
