Has anybody else come across this annoyance with nVidia cards?
(this should be a single frame filling the screen)
It seems to only occur when ALL of the following are satisfied:
If using full screen window, there are no issues other than the noticeable jitter on pretty much any content (even 30p stuff which should display properly). The jitter is quite surprising given that the GPU utilization is reported as 10% GPU, 10% Memory Controller, 20% Video Engine.
If I remember correctly, driver 276.28 was fine. I only switched because I hoped that the jitter was a driver bug (it wasn't).
Hardware:
XBMC Eden Final
AMD Phenom II X4 905e @2.5GHz
6GB RAM
nVidia Quadro FX 580 (equivalent to 9500GT/9600GT)
Realtek HD Audio
Windows 7 64-bit

It seems to only occur when ALL of the following are satisfied:
- XBMC is set to true full screen (not window or full screen window)
- The renderer is set to DXVA OR a file is playing with DXVA2 acceleration
- nVidia hardware and certain drivers (currently using 296.35)
