Mac touchpad scrolling interacts strangely with the shift key |
||||||||||||||||||||
Issue descriptionTo repro: - Fling on a long page - Tap shift While shift is held, we don't scroll. When it's released, we do. I'd expect shift to either cancel the fling, or not stop it at all. Another repro: - Hold shift - Touchpad scroll slowly I'd expect holding shift to either not impact things at all, or to completely prevent scrolling. Instead, it appears to prevent some deltas, but not all.

This seems to be broken at some point. For example, it works as expected in the following build: https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Mac/362232/ May be a bisect can help?

It's broken in 58.0.3029.96 and 60.0.3100.0. What version did you find it not broken in? It might have been broken by wheel gestures?

I picked randomly an older build from https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Mac/ For example build 362232: Chromium 49.0.2578.0 (Entwickler-Build) (64-Bit) Überarbeitung 8dfd114ecca6c1b2c2f28885e6d7173ddad7c1fe-refs/heads/master@{#362232} Betriebssystem Mac OS X Blink 537.36 (@8dfd114ecca6c1b2c2f28885e6d7173ddad7c1fe) JavaScript V8 4.9.103

Hi again, I did a manual bisect, and I found the following regression range: https://chromium.googlesource.com/chromium/src/+log/052c36a69d1d01b13b965ead4613c96d1806b835..3598c8bc9c56409f7c239c377fe6e42786d6aaa0 This CL could be the reason: https://codereview.chromium.org/2359463002

Yup, that's almost certainly it. Over to Dave. |
