Chromium change: https://github.com/chromium/chromium/commit/65c903d7aa0c4500b8cbfe475951a567125700d8 Suppress top toolbar captures on touch. Plumbs touch/scroll events from CompositorViewHolder to the top toolbar adapter. This captures to be blocked during scroll. In order to prevent old captures from being shown during this window, on demand controls locking is used. This must be done as fast as possible, when the touch starts, not when the render frame is being created, otherwise artifacts are visible. (cherry picked from commit 6136f92) Bug: 1374427
