Subject: [PATCH] Send GSB before switching to mainthread scrolling in smooth
|
||
|
|
scroll path.
|
||
|
|
|
||
|
|
This cl is the equivalent of https://codereview.chromium.org/2854683002 fix for smooth scrolling
|
||
|
|
path,if the compositor handles the GSB and during the scrolling we have to switch to main thread
|
||
|
|
since the compositor cannot handle a GSU a GSB must be sent to the main thread since the original
|
||
|
|
GSB was handled on the compositor rather than being sent to the main thread.
|
||
|
|
|
||
|
|
touchpad-scroll-impl-to-main.html is the test that forces switch from compositor thread to main
|
||
|
|
thread in the middle of scrolling. It used to get executed with --disable-smooth-scrolling
|
||
|
|
in this cl I've moved the test to a new virtual test suite that has default scroll animation
|
||
|
|
value.
|
||
|
|
|
||
|
|
I have removed the test expectations since I have changed the test and this might fix the flake.
|
||
|
|
|
||
|
|
subpixel-accumulation.html needs scroll animation to be disabled and that's why I had to move it to
|
||
|
|
a new test suite.
