Fix split-screen flash issue (9170ca82) · Commits · e / os / android_frameworks_base

For smaller size screens (such as 720p), in split-screen view, the size of DividerSnapAlgorithm.mTargets is 3, the divider line can only stop in the middle. As the original logic, when tapping recent, it will cause the top-docked activity to resize, leading to flash in some cases. To fix this, do not call startDragging in this scenario.
