Screen flicker on Chrome_public but not google chrome, Android
Xu, Xing
Hi, I installed two apks:
chrome_public: Chromium 49.0.2623.91 (Developer Build) unknown (32-bit); Flicker also happens on chrome_public 50.0.2652.0.
google chrome: Google Chrome 49.0.2623.91 (Official Build) (32-bit).
And reproduce steps:
1, Launch chrome_public or google chrome, type a url. when this finish loading. Kill chrome_public or google chrome.
2, re-Launch chrome_public or google chrome, see if screen flickers.
3, Run steps 2 many times. For chrome_public, you will see screen flicker at a low rate. For google chrome, no screen flicker at all.
Do you have any hints about how this happens?
Also, I attached the User agent diff of the two builds. Left is google chrome, right is chrome public.
