Problem with ZOOM-recorded video

Hi, I am Hyun Jae Jang and I currently working at the school.
For the remote class, I recorded my lectures using ZOOM.
I tried to edit my videos using DaVinci Resolve, but I got the big problem.

I recorded my powerpoint slide pages including "mouse cursor and laser point".
When I import the recorded video on DaVinci Resolve, the mouse cursors remained for 1~2 secs.

(you can also see example of screenshot here https://ibb.co/Ldry20Y)

When I watch the recorded video using Windows Video App or any other video app, there was no problem..

How can I fix it?
In my short knowledge, any frame blend options, interpolation or motion blur might be automatically applied... but I could not find options and fix this problem
