Martin Gräßlin 0bb587dcb9 Ensure PointerInputRedirection::processMotion finishes prior to warping ... Summary: Consider the following situation: we have three InputEventFilter linked in the sequence A - B - C. The input filters are processing pointer motion events. The expected behavior is that the new motion is processed in the sequence A -> B -> C So far this did not work correctly if the pointer gets warped during the processing. If e.g. filter B warps the pointer we get a motion sequence: A (1) -> B (1) -> A (2) -> B (2) -> C (2) -> C (1) The filters following the one warping the pointer get first the newer than the older position. This is obviously wrong. Unfortunately it is not just a theoretical condition, but a condition happening when interacting with the screenedges, which warp the pointer. This change introduces a PositionUpdateBlocker in PointerInputRedirection::processMotion to ensure that a processMotion call finishes prior to the next update. If the PositionUpdateBlocker is blocked the new position gets scheduled and processed once the PositionUpdateBlocker gets destroyed. With this we get the expected sequence for B warping pointer: A (1) -> B (1) -> C (1) -> A (2) -> B (2) -> C (2) This should hopefully improve the interaction with screen edges on Wayland. CCBUG: 374867 Test Plan: Added an auto test demonstrating the issue of incorrect ordering caused by screenedges. Prior to the change the test is failing.
