Xwayland dispatches tablet tool tip events immediately when they arrive. With compositors such as mutter and sway, it is not an issue because their libinput backends synthetize axis events before tip events. In other words, axis data and the tip status belong to different frames. On the other hand, kwin sends axis and tip events in a single frame (its libinput backend generates a single tip event with axis data attached to it). Since the tip events are dispatched immediately, they can have wrong information associated with them, for example tool position or pressure. It results in undesired "streaks" when the user presses the tablet tool against the tablet. See also https://bugs.kde.org/show_bug.cgi?id=479856.
