Regarding broken images in Android Chromium M39 with ARM Mali-T720

[Murphy Ma]

Dear Chromiumers,

I'm new to Chromium and here I have a broken image issue in Android using default browser. Please refer to attachment 1 for screenshot.

Android version: AOSP 5.1.1_r1(LMY47V)

Chromium version: M39 

GPU: ARM Mali-T720. 

I tried searching in crbug and found one similar case(I think) : issue 449488 which is reported with similar symptom and it's also using Mali GPU. I tried to make the modification as the commit tells, adding "disable_discard_framebuffer" feature but unfortunately it is not working.(Please refer to attachment 2 for the detailed diff)

I also tried to enable logging in Android Chromium by adding the command line switches parameters in aw_main_delegate.cc but only found some gles2 command decoder prints. (See attachment3)

Could someone help checking:

1. Is my problem the same as issue 449488 ? If you need more log/traces, please feel free to let me know.

2. If it's the same issue, is there anything else that need to be done apart from my effort in attachment2? 

3. Could some kindly share what is this "discard framebuffer" feature? What kind of framebuffers will be discarded and in what conditions will they be discarded?

Any help is appreciated!

Br, Murphy

Try it with updating your chrome build.

I don't think it will help much if just updating chromium version without modify chromium codes...
