aiman.ansari@, can you tell me why you gave Pri-1 to the issue?

This can be tested with #enable-mojo-loading enabled/disabled on M63 (the configuration is deleted on more recent versions).

The issue is observable both with / without mojo-loading. I attached movies. With LoadingWithMojo disabled, entries below "Android bionic libc" flickers. With LoadingWithMojo disabled, entries below "Material Design icons" flickers.

Hi yhirano,

I retested Stable #63.0.3239.132 with the mentioned flag 'Use Mojo IPC for resource loading' both in Enable/Disabled state.

And flickering is seen in both the case.

Attaching screen-cast for my observed behavior also. 

Thank You.
