Grayed out frames in videos

[pzych0]

Hello,

I have tried resolving this issue by myself with Google etc. But with no luck.
Now I am trying here to see if anyone can help me out.
The issue has started after I upgraded to Windows 10. (Upgraded from Win7 x64 couple months back)
The issue is that sometimes when playing a video, multiple grayed out frames pop up. (Stays at an average of 2-6 seconds)
Here is an example: http://s11.postimg.org/c1mqfmig1/Unavngivet.png
Funny thing is I can pause the video, even skip forward and back few frames, and the gray frames stay. They will however eventually disappear and video goes back to normal.
So far I've experienced that it happens with MKV and AVI files. I have not yet gone so far as tried another player, as the problem appears at total random, so would be almost impossible to debug.
What I have tried so far is raising the "File caching" setting, but with no change at all.
I've also tried changing the "Hardware-accelerated decoding" setting but again with no changes.
I don't believe that its codec related either, because as far as I know VLC doesn't use any external codecs.
In advance, thank you very much.
