Is it the same in -rc2? The bad patch that broke fountains was fixed
later, but you do have a geyser. I see random movements once a while too
on my fountain touchpad but it's been a long time since I saw that last.
My guess would be that the reinit changes the zero levels and therefore
the zero levels are wrong, but I don't understand that part of the
driver too well.
