1724728 - Screen flickering on Mali G76/G72

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Kevin Brosnan [Ex-Mozilla]]

From github: https://github.com/mozilla-mobile/fenix/issues/20733.

Steps to reproduce

https://streamable.com/lv92dj

1. Open any page
   Example:
   https://www.eurogamer.net/articles/2017-11-24-horizon-zero-dawn-override-cauldrons-locations-mounts-sigma-rho-xi-and-zeta-unlocks-locations-and-maps-4932

2. Screen will flicker everywhere on the page in form of a big black or white rectangle, depends on the theme colour.

It happens even if all add-ons are disabled. It starts only recently with the latest Nightly update.

[Kevin Brosnan [Ex-Mozilla]]

See a similar reports at https://github.com/mozilla-mobile/fenix/issues/20744 and https://github.com/mozilla-mobile/fenix/issues/20748 the second also mentions Mali G71

Comment 2

[loulouxiv]

I tried mozregression, but unfortunately the glitch did not happen in GeckoView Example... I could maybe manually git bisect the source code and build it... I could reproduce the issue after cloning mozilla-mobile/android-components and building-installing it from Android Studio but I am unsure what version I should use as the good commit.

What can I do to help fix this bug ? Any additional info I could gather ?

[Jamie Nicol [:jnicol] (PTO until 17/6)]

Thanks loulouxiv. We confirmed on github that this was likely caused by bug 1720169. Hopefully this should now be fixed for you, please let me know if that is not the case.
