Example of annotation with finger (works as expected) and with active stylus
(doesn't work)

SUMMARY
Hand written annotations (Alt+8) not working correctly when entered with active
stylus on a Microsoft Surface 9 pro and Lenovo IdeaPad Flex 5.
It seems the points of the line are duplicated and offsetted, leading to a
zig-zag pattern.

STEPS TO REPRODUCE
1. Try to annotate with hand writing (Alt+8) a pdf file on a Surface 9 pro, or
Lenvo IdeaPad Flex 5, using the active stylus.


OBSERVED RESULT
It seems the points of the line are duplicated and offsetted, leading to a
zig-zag pattern. If you annotate with a finger or a passive stylus all works as
expexted (see my attachment).

EXPECTED RESULT
A smooth line

SOFTWARE/OS VERSIONS
Windows 11
