I've experienced the same issue on Ubuntu 19.04 and 18.04 (but on other Linux distributions like newest versions of debian or manjaro too - both Gnome and KDE). Nevertheless it's working fine on Windows 10.
Is there any known solution to this problem? It seems that the touchpad is a certified one according to https://certification.ubuntu.com/catalog/component/input/4932/input%3ADLL079F%3A01044E%3A120B/ I can supply my configuration if needed but to give an overview: Dell Latitude 7480 Kenel: 4.19.28 Dell BIOS: 1.14.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1754052 Title: Dell Latitude 7480 press shift keys triggers random mouseclick when `Tap to click` enabled on touchpad.
