Jason, please confirm if this is indeed a bug or an UI effect.

This is likely a core graphics layers regression, not a 3rd party website bug. We've seen bugs like this before in this area in regards to scrolling content.

Joe - Any ideas why we the links shown on the screenshot are disappearing during scrolling?

Matt might know!

This reminds me of bug 800041 a bit.

Probably best to try get a regression range.

I have been doing a regression window on Unagi v1.1

Checked builds:
2013-05-20-07-02-07
2013-05-27-07-02-08
2013-06-03-07-02-07
2013-06-10-07-02-06

All of these experienced the same issue with the Thesaurus.com app.

Would you like me to continue going back?

Comment 8

[Jason Smith [:jsmith]]

Yes. Try testing builds over on a month by month basis instead of weekly for this bug. I get the feeling that this may have regressed a while back.

Comment 9

[Jason Smith [:jsmith]]

Talked with Dwatson about this. We're seeing this issue reproduce all the way back in January, so 1.01 probably has this same bug. I don't think there's value to going farther back than January builds wise for B2G, so I'm pulling the regression window keyword.

Probably isn't worth blocking on this if we've shipped a Firefox OS release with this bug in 1.01 then, so I'm pulling the blocking nom as well.

I think this is simillar to bug 792966

Thesaurous.com(actually m.dictionary.com) creates some thebes layers with around 16 height,
and ShadowLayerForwarder::PlatformAllocBuffer() attemps to create GraphicBuffer.

So I added the condition for height(less then 17), then dissapearing is not reproduced.

So to make sure I understand comment 11, this is something the developer needs to fix?  I can send the developer a message as long as I can copy/paste it from somewhere.  =]

If more complex communication is needed, then partner engineering would be better to take the lead.

No, this is not an app developer bug. This is GFX bug in the platform.

Jason - should this bug be closed now?  In other words is it fixed in current releases?

Comment 15

[Jason Smith [:jsmith]]

No.

Comment 16

[Karen Ward [:kward]]

Jason, Do you have a suggestion on who this should be assigned to?

Comment 17

[Jason Smith [:jsmith]]

This bug isn't a priority right now.
