I found a bug in the file manager. When I go into it and scroll towards a HEVC x265 video file it makes Kodi sluggish and even crashes Kodi with the sad face screen.
I tested it in multiple cases to make sure it was the x265 videos (tested three different videos so it is not specific to a broken file but the format in general)
Also note I don't have to open just be scrolling through the file manager towards it. In one case a put one video in the middle of a folder with over a hundred random files and it only happened when I got to the actual HEVC file.
Note going into the file manager then opening the context menu and switching media fixes the problem and I can scroll to the files and start watching them.
I'm using the newest build from this thread on a Raspberry Pi 2 in the file manager I'm going into a NFS mounted directory (mounted by autofs on a OS level not by Kodi) the NFS server is a Linux computer.
I never had any problem scrolling past these files before using these builds.
