Public bug reported:
Using both a dell, and Lenovo laptop, the built-in touchpad will incorrectly
detect certain gestures and actions.
When scrolling with two fingers, it will act as if I am doing a three finger
gesture to zoom, similar to the pinch and zoom gesture.
If I am trying to tap with two fingers, to open a context menu, it will
act as if I tapped with three fingers (middle-click button simulation).
Sometimes when I try to use the built in tap-to-click (bottom left of
the trackpad), and tap that region, it will act as if it is inverse and
act as if I clicked on the right lower region.
I am able to verify that my touchpad works as intended by running a live
USB environment of Ubuntu 24.04
When scrolling on websites, it will zoom in instead of scroll up or down.
