[Jan Gruuthuse]

1st impression: OpenGL display seems to be more stable (green/purple distorted distorted image in avidemux playback)

Perhaps time for small benchmark section in avidemux 2.6.8? So you can decided what the best combination is how to use avidemux. As you can now choose a combination for:
Display: vdpau or va-api, with or without opengl support
HWaccel: (VDPAU or LIBVA) on nvida.

LIBVA: not certain if this would be the case. intel GPU on cpu is disabled/not used in my current setup.

libva is just a wrapper over vdpau in that case
