Hi, I have had a similar problem on my Z3 compact twice since september. But only after the phone has been on for a month or so. Just had it the second time, and the phone's uptime is now ~650h.
I use swiftkey keyboard. Last time and this time it helps to minimize the keyboard when typing gets messed up by the problem, and bring up the keyboard agin. But the issue returns shortly after anyway, and scrolling remain difficult.
Last time it happened, I just restarted the phone, and that's what I'll try this time too. The fact that restarting the phone get rid of the problem indicate that it is a software problem and not a hardware problem. So either some app, or in the device specific Android itself.

And while googling for this, I also found someone saying turning off the touch-screen-to-wake-up function in the settings got rid of the problem. I have this feature enabled.

I've been getting this problem on my Z3 compct as well.
Symptoms: Touching the screen results in unexpected behaviour:
- very fast scrolling of pages and sometimes scrolling in the wrong direction
- touching a button doesn't register or takes unusually long
- pressing backspace/enter while typing results in wrong keyboard input and sometimes appears to type random text as if I was using gestures (like a swype keyboard).
Occurrence: First noticed it maybe a month or 2 ago. Since then I've noticed it occurring at random maybe once every few days. I do recall having charged the phone some hours prior - maybe some electrical charge/static buildup?
Temporary fix: Sometimes the problem goes away on its own, but other times I've had to restart the phone to get back to normal.
My settings: Glove mode and tap to wake has always been off. Gesture mode was on and I don't want to disable as I use it a lot. I also don't think gesture mode is the cause as I sometimes get the problem while I'm just scrolling pages. I do use a simple screen protector but I've used those with other phones and never had an issue.

suggests stopping the com.sonymobile.touchscreen.touchfilter running process. Not sure what side effect this has but I'll give it a go.

I have the exact issue as iFloi, only one one side of my keyboard letters stopped working including I/N/Period.. I swipe over it and it literally skips these letters. The unit is going back to Sony for repair will update once I hear back. I've had this phone since October and had no issues.
