Not sure why this cannot be added to the Plex server thread as its really a Plex Server issue but it doesn’t meet any of the sub threads criteria. 
I have a Plex server, with a Plex Pass. The server consists of an IBM x3550 M3, dual x5660’s, 64GB of RAM, an IBM M5015 raid controller with two Samsung EVO 860 250GB SSDs, and a LSI 92xx external SAS raid controller with BBU and 1GB of cash connected to a Dell M1220 loaded with 5TB SATA drives, and Windows 2016 Server Standard (fully patched).
I stream HEVC 265 connect. Every movie I have watch after the latest patch there has been a lot of buffering issues, sometimes the movie image freezes while the audio continues then the video catches up. Or in the worse case the whole movie starts buffering. 
My brother who has a Nvidia shield (patched) was direct playing everything off my server, not its transcoding everything down to 264, and transcoding the DD5.1 or DTS 5.1 down to something else. 
Would have been nice if the developers at Plex would have QA’d their installer before releasing it, because it looks like they released a buggy package, or maybe that was their intent to release it full of bugs? IDK. 
Thanks,
