Your issue is missing necessary system information.

I had a similar effect after saving the plugin settings for the fist time - setting contrast and saturation were set 1 and I hat to set them to 10 again to restore the "normal" image.

Should'nt those variables be initialized to the value 10 instead of 1? https://github.com/pesintta/vdr-plugin-vaapidevice/blob/master/vaapidevice.cpp#L76

[rofafor]

The min/max/default values and the step function are defined in the driver, so changing the initialization value to another one might break other hardware. The driver values are read here: https://github.com/pesintta/vdr-plugin-vaapidevice/blob/master/video.c#L2458 . Please, check what your driver states about the default value: is it 10 or 1 or something else...
