Occasional white flash / glitch when switching tabs in e10s


(Core :: Graphics, defect)

Not set





(Reporter: ehsan.akhgari, Assigned: handyman)


Sometimes when I switch tabs in the e10s browser, I see a very short white flash, and sometimes it seems like there is some corrupted graphics content being displayed momentarily (usually with some kind of a gfx pattern repeated to fill the entire content area.

I don't have an STR, but this happens fairly often during normal browsing.

was this supposed to block m2?

I don't think we decided officially but I'd say it definitely should.

Oops... I was thinking of a different bug.  I do not think this is M2.
In addition to tab switching, I've noticed on some sites that the page content takes a half-second or so to load. During this half-second the background color of the page is all that is visible (so, white in many cases, but can be any color the designer used), then the content of the page loads. This happens even when the whole page is in the cache. It happens every single time. It does not happen for all sites, though I would be curious to know what is causing this. A site I am currently developing locally does this, as well its staging counterpart online. It is not JavaScript-heavy.
This actually happens on this very bug tracker site. It happens every single time, too. When disabling e10s, pages loads as expected, without that delayed flash of content. The background color is the current one on the site.
I'm on OSX Mavericks with retina display. I'll test this on win7 64bit and mention whether it happens there as well.
