This might be related to bug #445419 I'm using Falkon with a touchpad, because Falkon (or its backend) is the ONLY web web software that is fully usable with touchscreens. However, the GUI/Qt interface itself doesn't seem to be optimized for touchscreens. I request in this report to add a touch mode display, similarly to Firefox and Plasma, which really requires padding GUI objects.
