Comment 149 for bug 308191

@Jim Rorie

Thank you for the hint with post #8. I was able to reproduce the cursor jumpiness both with the script and the newly installed package (when two-finger scrolling is turned off). It turned out that the jumpiness is more extreme with the package, the cursor really makes a huge leap and continues to move even further when I already took my fingers off the touchpad. I really think this might be related to the scrolling jumpiness.

When I activate two-finger scrolling when the package is installed and perform the steps described in post #8, the window would scroll up or down.

I hope this information helps to fix this issue. Please let me know if you need further information.
