Browser can't seem to handle content heavy websites, especially if the site contains media clip

Comment 4

[Gregor Wagner [:gwagner]]

Is this a regression, meaning it works on 2.1?

Comment 5

[No-Jun Park [:njpark]]

So I tested it with 2.1 and 2.0.  In 2.1, the page loads, and the video starts playing automatically, but the browser OOMS after a minute or so.  Also it OOMs when there are rapid scrolling or orientation change, but it handles much better than 2.2 or master.

In 2.0, the video plays to the end, and scrolling/orientation changes does not cause any crashes.

IMO, there is a general memory footprint increase in 2.2 and onwards.  In the bug 1133144, camera oom issue was raised, but it seems that other issues might contribute to it as well.

I was attempting to reproduce this issue but had no luck on central (latest and a build around the time of the one in comment 0) or on 2.1 but No-Jun has completed the request now so removing the tag.

I think there have been several websites that have been reported to OOM.

Here is one example. The Tumblr website also encounters an OOM when scrolling. Please see bug 1063854

Triage is blocking because this reads like a performance regression.

Hi Candice, need your help to follow up on this, thank you.

Comment 10

[Gregor Wagner [:gwagner]]

Can we test again? We fixed some gfx issues.

> Can we test again? We fixed some gfx issues.

This issue is still occurring on today's Flame 3.0. The issue seems have a higher repro rate for Wifi connections - higher chance to LMK if contents load in faster, it seems.

I reproduced the issue 1 out of 3 on a 2/3 build, and 1 out of 1 on today's build.

Taking to investigate the cause.

Comment 13

[Chris Lord [:cwiiis]]

Can't reproduce this on master with the steps from comment #0, will flash to 2.2 and try there.

Comment 14

[Chris Lord [:cwiiis]]

Can't reproduce this on 2.2 either... Reporter, can you still reproduce this? Perhaps it was fixed by recent gfx uplifts?

I'm trying this on a 319mb flame-kk.

It might be that I get a different CNN being in the UK, the video doesn't auto-play for me certainly.

Comment 15

[No-Jun Park [:njpark]]

I just checked it again on the latest master branch, and I do see the performance improvement compared to the build that I found it in. Now it OOMs only when I also perform pinch actions and screen rotation - simple scrolling will not OOM.  I think the core issue is still there, but it is actually now being tracked by bug 1128042.

So I think we should close this bug and point to the one that's currently being worked on, because the bug does not occur when strictly following the STR.

[Hermes Cheng (inactive after July 27, 2015)]

I cannot reproduce this on 2.2 branch either.
