Does H.265 make more motion echo than H.264? any solutions?

I had to render a video, which I made with After Effects, containing a background-transparent photo moving fast.

I used H.265 since ios somehow didn't show h.264 mp4 videos in gallery a while ago (heard that this issue is no longer a problem), then I got this weird echo effect.

Somehow moving object(in this case, it was "background-transparent photo") remained in next frame in low opacity, and the next frame appeared in same conditions, resulting with two half-transparent images overlapping.

same thing did not happen when I rendered my composition in H.264.

Below are some examples how my work looked (did not turn on "motion blur" option):

▼H.264

▼H.265

see the circle remaining half-transparent and the next frame appears in same condition too?

these two are exact same compositions, exact same time, but only render options were different.

I used Media Incoder to render these.

is there anyone suffering with same problems, and any solutions for this?

or is this one of the H.265's characteristics?
