790723 - Zooming/panning on simple HTML page makes it turn black/green and messed up

Status: RESOLVED DUPLICATE of bug 790764

(Firefox OS Graveyard :: General, defect)

Description

[Benoit Jacob [:bjacob] (mostly away)]

This is on a Otoro ICS phone, with a B2G build from today, default config.

Initially, the page displays properly. The trouble starts when I zoom/pan: instead of zooming/panning correctly, this turns the page into a magma of dark green on black background, with some text (apparently, the text that was colored in the original page) still visible but with a wrong olive/green color, and most of the text (which was not colored i.e. was black) no longer visible.

Hitting this while writing the ATC conformance test --- in this case, perhaps because the page is very tall, the problem occurs right away on load.

A similar bug is visible on google.com -- filed bug 790764, might be a dupe.

I think it may be.  there's lots of invalidation issues when zooming and panning.

Benoit, if this is a dupe of bug 790764, is it now fixed?

I haven't made a b2g build recently, but since it seems fixed for you, and there is a good theory on what fixed it, let's close it -- we'll reopen if needed.
