Problem with HEVC/x265 videos (1080p/720p)

Goodmorning,
i have a problem with HEVC/x265 videos (1080p/720p)

If I play the video from the beginning I have no problem, if I play the video from where I had stopped KODI crashes.
what is the problem in your opinion?

My system:
WIN7 PRO 64bit
CPU Intel i3-4330
GPU Intel HD4600 (integrated in cpu)

Many thanks
