X96max 4G/64G Playing UHD issue

Latest nightly build installed in SD.
There is a problem with playing UHD video.
When I press the up buttonor right button, skip the video
Kodi will crash and it will take 1-2 minutes to return to the main page.
before play UHD video, I run top in SSH.
I saw that kodi.BIN will disappear and then restart

If I use kodi in android,everything is OK.
I press the up button many time,kodi can skip smooth .
