After some uptime (most likely after going out of suspend) the touchscreen driver behavior might get unstable. For example, while scrolling some elements might get highlighted like there's an invisible cursor standing there. Dmesg shows some issues with iptsd too:

For example, here:

It is not a critical bug which would stop iptsd completely, but still might be a bit annoying. Sometimes it doesn't work after booting the system, so i have to press the power button to suspend the tablet and after that unsuspend it, so it gets fixed.
