I investigated a bit and reverting the fix for issue #774938 (1) fixes the problem and my touch / stylus work correctly.
So the regression is introduced by the following patch
503_fix_masked_transformed_valuators.patch
Using a Lenovo X201T with Wacom touchscreen. Let me know if I can help in any other way.
