Certainly so for at least the last three to four years.
I don't believe it's a library issue as the error messages in dmesg - which are far more disturbing than those in Xorg.log - come directly from the psmouse module. It would appear ELAN trackpad drivers are generally in a very sorry state across the board. In my very rare and limited use of Windows I remember having a similarly abominable experience, albeit due to other symptoms. With Synaptics trackpads, although not perfect, I have yet to experience anything as hellish as this.
