On this subject 'video shudder' or what ever you call it.
As if the display jumps or misses frames more noticeable with h265 or 1080p files. It's seems something is not well and I've tried numerous things to pin it down, and so far the issues is unclear. I noticed it a while back, and attributed it to bad encodes and largely ignored it until the other night I decided to watch an anime with subs and the shuddering was impossible to ignore and knowing how many people were leaving messages, I decided to look into it deeply and more or less came up stumped.
My system is kinda old, the cpu is an older i7 and the graphics AMD Radeon 5770 HD pushing to a PC monitor or flipping the display over to a LG flat panel through a Onkyo 5.1 AVR. I noticed that in Jarvis...my hardware acceleration not longer worked. The gfx software as follows

Just recently updated this week in the hopes of a cure. The O/S is windows 7sp1/64 bit, and a fairly healthy amount of memory in both the graphic card and system.
Now for the unusual particulars, spent a bit of time changing this & that, elimination or the advanced settings, then back in, changing the defaults, playing with the audio, checking play back with various players (VLC, Windows Media Player, MPC-HD as well as Kodi). Thought I might be just at the cusp of the limits of the graphics on this machine. Every once is a while I'd check the various jitter videos.... and every once it a while it would be 'smooth' as silk, and I'd proclaim... I found the bugger! and attribute it to whatever I tried or toggled.
At first I thought it might be related to the audio... at one point I had a smooth playing video on the PC monitor and then flip it over to the TV and see the jitter. Ah I'd say.. got you. Nope flipping back to the PC re-starting and still got the jitter. Sometimes it launched with jitter and sometimes smooth as silk, even book marked a passage that made smooth vs jitter obvious and would use that as I made changes in this that and everything.
I've got a collection of 1080p H265, where the jitter makes it impossible to enjoy the video.. I overclocked the gfx card, turns up butter smooth... but sometimes not (with the same settings!) so I'm a bit perplexed. The debug log is not giving up a clue, the only advanced sign is the entire interface, mouse included doesn't seem snappy, maybe lagging one might say.
To make matters worse, the Independent stand alone players are fine, and the old XBMC 13.2 build I have works fine but doesn't have h265 capabilities. I'm biding my time, looking to Krypton for the solve at this point, for people that don't want to wait, look back at Isengard 15.2
