cc: Flush after every tile task set completes.

Flushing in PrepareSendToParent isn't sufficient because that's skipped
when there's nothing to draw, and there can be nothing to draw if we
haven't flushed.

Flushing after all tiles are done is too late. The all tile set can be
very large for even simple pages.

Flushing after every task set and in PrepareSendToParent is reasonable
and seems to work well.

This bug is marked as RB-Stable but one of the bugs duped into this was RB-Dev. Are we doing a M62 dev release soon that we can merge the fix to? The fix landed on trunk yesterday isn't in a canary release yet.

I should've mentioned that this affects Android (not just webview).

Tested the issue on Windows 10 (Dell Precision M3800) using Chrome version M63 - 63.0.3208.0 as per the issue mentioned in original comment. Observed that issue is working as intended (Dropdown list doesn't appear to be blank). 

Issue is observed only on touch devices.

Adding the label 'TE-NeedsTriageFromMTV' to verify the issue on Mac and Linux touch devices.

Thanks.

 Issue 762968  has been merged into this issue.

I don't think this is a dev blocker - it's annoying but things still work.  That said it's a beta blocker, I don't think it meets our quality bar there.

We'll be shipping an M62 dev today cut from branch last night, so you missed that cut - but we'll be doing another next week before moving to beta so just make sure the fix is verified and then merged before EOD tomorrow and you should be OK.

 Issue 762465  has been merged into this issue.

For what it's worth, the bug was already in Dev -- see  Issue 761270 . Agree this should block Beta, not Dev.

Your change meets the bar and is auto-approved for M62. Please go ahead and merge the CL to branch 3202 manually. Please contact milestone owner if you have questions.

Updating summary to reflect the wide-ranging and serious impact of this bug - it basically destroys the scrolling user experience on most pages in Chrome.

Removing RVG and comment with google internal URLs - users/outside-developers will want to refer to this issue given it's broad scope and large impact (I'm sure many hours have already been wasted identifying this bug as the root cause of all the other duped issues for related symptoms).

Confirmed fixed in 62.0.3202.9.

Fix merged to M62, Issue doesn't repro on latest M62- 62.0.3202.16 as per the steps mentioned in comment#0. And issue doesn't repro on latest M63: 63.0.3212.0

Tested on : Pixel XL/(NJH47D), Nexus 5X/(NRD90R), Samsung Galaxy J2/(LMY47X), Micromax Q372/5.1 (LRX21M), Sony Xperia XA/6.0(33.2.B.2.93), ASUS_Z010D /6.0.1(MMB29P), Htc Desire 630/6.0.1(1.00.400.3)

Thanks!
