App touch input is delayed compared to Show Taps

[Curi0]

I've enabled "Show Taps" in developer options and the touch input apps receive is delayed compared to the white circle. Here's a screenshot showing it with AOSP's TouchLatency tool but it happens with other apps too.

I thought it would be the touch resampler causing it so I disabled it with "ro.input.resampling=0" but that didn't improve it. Any idea what's the source of this added touch latency ?
