1650954 - Crash on pinch zoom in/out repeatedly on a page having background-repeat and transforms

Status: RESOLVED FIXED

(Core :: Graphics: Layers, defect, P3)

Description

[Hiroyuki Ikezoe (:hiro)]

Attachment: crash.html

I am totally unsure this is a valid bug or not because it seems the crash is caused by lowmemorykiller on Android.

Steps to reproduce;

1. Open the attachment file on Fenix (I used nightly)
2. Pinch zoom in/out repeated even if the content is irresponsible

The page uses a static transform value, rotate(45deg), if it's animated, the crash happens more often.

Note that I couldn't reproduce the crash on Fennec.

Do you have WebRender enabled or disabled? Or does it happen with both?

Comment 3

[Hiroyuki Ikezoe (:hiro)]

I thought I was initially testing on WebRender, but it seems not. I now tried to reproduce it on WebRender, but I couldn't produce it at all.

So, it's non-WebRender specific. I am on pixel 3, FWIW.

Hiro, can you please attach a stack trace of the crash?

Comment 5

[Hiroyuki Ikezoe (:hiro)]

As I said in comment 0, it looks it's killed by lowmemorykiller.

Comment 6

I am not sure where the memory allocation is bloating, but the crash doesn't happen on WebRender.
