Been noticing this over the past couple days and just narrowed down the specifics. I tether using PDAnet often and hop back and forth between using the computer and my phone. However, with my phone plugged in (charging) my touch screen acts like it's already being touched somewhere else. Preverted thoughts aside, it constantly uses multitouch controls like zooming in/out, entering a random keypress after I hit a letter, etc.
Any idea what could be causing this or proposed solution besides reflashing? I haven't experienced this outside of MIUI but I did also change kernels when I flashed. Just really hoping the kernels not the issue.

Edit: D1 with MIUI 1.2.11 and Slayher1.2g kernel.
