So, I'm using a PREEMPT_RT SMP kernel and I still get the same problem,
only much less frequently than with PREEMPT_DESKTOP. The problem does
not start right away after I boot, it takes around 5 or 10 minutes to
show up (with both options). Right now I'm not getting frequent screen
blank due to the screensaver and I'm typing this without autorepeats,
don't know for how long :-)

I left this running for a while:

#!/bin/bash
while true ; do
START=`date +"%s"`
sleep 10
END=`date +"%s"`
let DIFF=END-START
echo "$DIFF" >>time
echo "---"
done

I'm attaching what I found when I got back.
