Ok, I merged with current andy-tracking to get a current ts filter chain but it is still the result. I produced a little example for the current problem with touch_test.py. I only pressed my finger on one point of the screen. The app reports: Move: (352, 242) Down: (352, 242) Move: (380, 253) Move: (394, 257) Move: (409, 268) Move: (420, 284) Move: (426, 291) Move: (429, 295) Move: (430, 298) Move: (433, 301) Move: (433, 302) Move: (434, 302) Move: (434, 303) Move: (433, 303) Move: (434, 303) Move: (433, 303) Move: (436, 304) Move: (435, 304) Move: (434, 304) Move: (433, 304) Move: (430, 304) Move: (431, 304) Move: (434, 304) Move: (433, 304) Move: (434, 304) Move: (435, 303) Move: (436, 303) Move: (434, 300) Move: (430, 292) Up: (430, 292) So the cursor moves up to top left corner while I am press one point of the screen. Any hints which calibration of the filters is wrong?
