example

before , after.

note moderator on post category , driver testing results:

i using vaio z-flip. can confirm issue both active n-trig pen packaged laptop vaio , sp4-pen. reason post left in powerpoint forum. can confirm ink smoothing works in onenote, therefore confident not driver issue issue not understanding how use turn on or trigger ink smoothing in powerpoint application. or powerpoint not recognize active pen correctly seeing how did correctly before not understand why no longer does. still both lead powerpoint or powerpoint settings being issue not hardware or drivers; seeing powerpoint can perform correctly given right circumstances(presentation inking mode). second major point after refresh worked smoothing after second refresh stopped working without changing drivers or installing y new hardware. leads me believe powerpoint setting or issue rather driver issue, since not see why windows 10 refresh different second time performed. third if works in onenote , in presentation mode powerpoint why not work in slide editor mode powerpoint. last if issue can solved installing sp4 drivers on vaio hardware, suspect not work, have tried altering surfacepen.inf surfacepro4_win10_161521_0 driverpack  , turned off driver enforce check , installed hacked driver did not work. other driver combos have tried listed below. between each test case drivers, devices , drivers in question uninstalled , forcefully removed driverstore ensure no driver leftovers caused multiple version driver issues.

1. microsoft driver set pulled via update devices. note surface pen driver dated '06 ver 10.0.15007.1000

2. vaio drivers devices. (manufacture shipped settings)

3. wintab-64 variations on both of above.

4. installed surfacepen(base, clickfilter, integration, settings) drivers, via .inf files, surfacepro4_win10_161521_0 install correctly.

5. date drivers possible devices device manufactures

6. beta drivers devices possible device manufactures

7. office 365, office 365 slow insider, office 365 fast insider

8. altered .inf sp4-pen driver bluetooth hoping newer '06 appears driver work correctly on sp4 since received error code 10 device not start. perhaps driver alterations incomplete.

after these test cases not reproduce smoothed ink results present after first refresh. being systems admin , software engineer believe that capable if need more information, testing, or complex solutions.

***post moved moderator appropriate forum category.*** (sp4 drivers , hardware)

 please see above comment consider if , should moved. computer not sp4.
***post moved poster*** (office 365 powerpoint)

so have done more research. able determine issue introduced powerpoint 2016. did refresh , determining office 2013 installed. after updates office 2016 issue appears.

1) can there insight why , or how pen input during slide editing mode degraded in powerpoint 2016 in comparison powerpoint 2013?

2) can powerpoint 2016 during slide editing given similar inking method powerpoint 2013; or inking onenote 2016 works; or inking mode during presentation mode works?

3) there way revert powerpoint 2016 use inking method 2013?
