Able to reproduce this issue on reported version 64.0.3282.186 and latest stable 65.0.3325.146 using Windows 10, Ubuntu 14.04 and Mac 10.13.3. But issue is not seen on latest canary 67.0.3364.0. Hence providing reverse bisect info. Last Bad Build: 66.0.3344.0 First Good Build: 66.0.3345.0 You are probably looking for a change made after 535635 (known good), but no later than 535637 (first known bad). CHANGELOG URL: https://chromium.googlesource.com/chromium/src/+log/e04a14f4769d6b33b32686ccc3414e917a625ae7..a5676deb1e679035678bc1ed997518cd226378b9 Probably fixed by https://chromium-review.googlesource.com/857902 @Skobes. Please merge the fix to M-65 if it is safe. Adding RB-Stable for M-65. Please change if not the case. Thanks!

This is broken on M64 so we're not going to stop M65 further roll out for this. Pls let us know ASAP if there is any concern here.

More specifically, this is fixed by enabling root layer scrolling in r535636 (66.0.3345.0), correct? (As opposed to WontFix, that is.) Updating labels to reflect that it's fixed in M66. |
