I am currently running XBMC nightly and have been working with fritsch via the XBMC forums to diagnose this issue. My current setup is as follows:
AMD A6-3500 APU with Radeon(tm) HD Graphics 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] BeaverCreek [Radeon HD 6530D] 00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] BeaverCreek HDMI Audio [Radeon HD 6500D and 6400G-6600G series]
Ubuntu 13.10 running 2.13-rc1 with mesa git (10.0~git201311181342.37827~ubuntu13.10.1)
My HTPC is connected to a Denon AVR-991 then connected to a Panasonic 50" Plasma. The Denon is setup for 0-255 levels and the HTPC via XBMC is set for 16-235 due to it being "darker" than normal after the leap from windows. Recently I've added an xrandr setting to turner Dither to ON since before the setting it would occasionally switch black levels through video play and with the new setting it ONLY does it on startup of video playback and then corrects itself 2-3 seconds later.
I am in the process of taking a video now for reference and will upload it later today.
