Build: Fennec/13.0a1 2012-02-15
Device: HTC Desire (Android 2.2)
Steps to reproduce:
1. Go to Facebook.com and wait to be redirected to m.facebook.com.
2. Wait for the page to be completely loaded and scroll the page or change the device orientation.
Expected results:
The content is correctly displayed.
Actual results:
The page becomes completely blank. Changing the orientation again repaints the page correctly but when doing a new scroll or orientation change the page becomes blank again.
Notes:
- The issue is not reproducible on the Android browser.

I was just about to file this too. I see it on the Galaxy Nexus (Android 4.0.2). Attaching a log but I'm not sure if there's anything interesting in it.

I'm also seeing this bug on the Galaxy Nexus (Android 4.0.2), but for me it's much worse.
Basically every page shows up blank for me, except about:home.

Requesting higher priority because it is a top-site issue.

I think I can reproduce it with this testcase.
Steps to reproduce:
- Change orientation to horizontal
- Change orientation to vertical
- Change orientation horizontal
After that, the text on the page has become invisible.

Ok so the issue is the styling
They are serving Fennec this: i.img u{position:absolute;top:-9999999px}, and Fennec chokes on the negative value.
This is very much similar to bug 714709.

So is this a layout issue, or bad UA sniffing on their end?

This is a Fennec layout issue, see testcase and steps to reproduce in comment 6.

Ah, I see. That seems highly unlikely to be a layout issue. Much more likely, we're ending up with a cairo context in an error state or something.
