Drag shadow freezes on the drag start position |
||||||
Issue descriptionChrome Version: 62.0.3187.0 Chrome OS Version: 9844.0.0 Chrome OS Platform: Chromebook Plus Steps To Reproduce: (1) Try to drag a file by long-press + dragging touchscreen. Expected Result: Drag shadow move as the pointer (a finger, or a stylus pen) moves. Actual Result: The drag shadow stays at the start position, and it stays even after releasing the touchscreen. How frequently does this problem reproduce? (Always, sometimes, hard to reproduce?) 100% What is the impact to the user, and is there a workaround? If so, what is it? [esc] key can cancel dragging. If you touch the screen again, you can continue dragging the item normally.

This is not a specific issue with the Files app. This can happen on other drag & drop operations using touch, such as text edit. Steps To Reproduce: (1) Browse as guest. See the browser appears with "You're browsing as a Guest" page. (2) Select the text in the browser by tapping it once and [ctrl] + A. (3) Long-press the selected text by touch, and move it around. Expected Result: The dragging shadow of the text moves as you move. Actual Result: The shadow stays there.

Based on my bisecting result, I think this issue appears after https://chromium-review.googlesource.com/c/613700 ad908bef2e858b5786328b11b7b83f9a1d74fbb7 Mon Aug 14 19:57:02 2017 +0000 Scroll/Fling cannot happen after long press. --> positive 91858a77d72fe1a020188114b4834a96324e7b6b Mon Aug 14 19:55:53 2017 +0000 Move longtask-timing test failures to TestExpectations --> negative

Sahel, may I ask you see if this is relevant to your change? I originally found this in the Files app, but found that it also affects text editing (and possibly other operations) in browser.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/48d76dc81628ffda0c4c56ac06e2dcbdecb57034 commit 48d76dc81628ffda0c4c56ac06e2dcbdecb57034 Author: Sahel Sharify <sahel@chromium.org> Date: Wed Aug 16 17:57:44 2017 Revert "Scroll/Fling cannot happen after long press." This reverts commit ad908bef2e858b5786328b11b7b83f9a1d74fbb7. Preventing scrolling once long press is fired, breaks drag and drop.
