As i've said, driver is up to date.
When i install the nVidia drivers i remove (don't install) all the 3D stuff. I only install the video core driver and the high definition audio driver.

I meant 3D acceleration not stereoscopic 3D. It's not possible to do not install 3D acceleration stuff

I don't know what more i can provide. If you have any information tool or test program you want me to run, tell me.

Please download GPU-Z utility. Launch it, then run Kodi, enable Use fullscreen window ... in the settings, start playback of movie and see GPU loading graph at second tab in GPU-Z. It should be about 25%-40% (depends on hardware)

I don't think it's relevant or have any effect, but the PC running Kodi is totaly offline.

it doesn't matter.

You've found no clues in the both debug log ?

no any clues in the logs.

As a temporary solution I suggest to set Enable HQ scalers for scaling above to 10% value in Setting -> Videos -> Acceleration. No need to scale 1920x1080 movie to 1920x1080 screen it's useless work
Thanks.
