How about f.lux or other programs that interact with the GPU? This looks like Optimus or other odd architecture issue but of course you are using AMD with a dGPU.
Edit: The issue is getting the frame from the decoder to the GPU, usually a memory bandwidth problem (that can be caused by drivers or software along with hardware limitations).

Those options didn't make sense.
There is no other programs that interact with the GPU.
After my testing,I found it that only 10bit videos lag too much.Is that really a memory bandwidth problem?
