--- Comment #4 from Nate Graham <n...@kde.org> --- The Synaptics touchpad drivers can send fake scroll events, but Libinput deliberately does not, delegating that to the UI toolkit. Yunhe, which drivers were you using? I was able to reproduce this using Libinput, which means the culprit would be somewhere in Qt. -- You are receiving this mail because: You are watching all bug changes.
