Bug 447668

SUMMARY

When panels and docks are hidden on Wayland, it is impossible to show them by only using a touchscreen. On X11, it works because the mouse cursor follows the finger on the screen. On Wayland, there is no cursor anymore under the finger, thus panels and docks are not aware the user wants to show them when touching near a screen edge.

Similar to bug #447666 affecting Plasma panels. I reported it here as well because I figured the technologies might be different.

STEPS TO REPRODUCE
1. Add a dock or a panel
2. Hide it by placing a window over it or by setting it to auto-hide
3. Touch the screen near the dock/panel position to show it again

OBSERVED RESULT

It is impossible to show a hidden panel or dock with a touchscreen.

EXPECTED RESULT

Users should be able to make hidden panels/docks appear either by touching near the screen's side where the panel/dock is, or by doing a small swipe gesture. If opting for a swipe gesture, it should not interfere with screen edge actions by using different distance thresholds (small to show panels/docks, longer to trigger actions).
