The “Force Peak Refresh Rate” setting in Developers Settings is the only setting i can think of, helps smoothing other things out a bit for me too. I don’t know if this actually increases the sensitivity, but i guess it’s worth a shot.
I have the e/OS version of the FP6, so i don’t know if the Google version has features added somewhere else.





“Parts of the phone reached a scorching 130° Fahrenheit, which is hot enough to burn your skin after about 30 seconds. During a few stress tests, the phone completely closed all apps and disabled functions like the LED flash to manage heat”.
I know this is during benchmarks and the average consumer would not get anywhere near this, but still… 130°F (54,44°C)?!? I think 113°F (45°C) is already a little too warm to be comfortable…
