Finder Icon Association Issue

The problem is that the icons on any file don't update when the default application is changed.
I was able to fix it but it only fixed the existing icon previews, any other default program change would result in the same problem

What happened was, that I ran 3 the following 3 commands in Terminal

$ sudo find /private/var/folders/ \
-name -exec rm {} \;

$ sudo find /private/var/folders/ \
-name -exec rm -rf {} \;

$ sudo rm -rf /Library/Caches/

They did refresh everything, and all the icons/previews were back in place as they should've been.
In my case

1) I had some MP3`s not displaying artwork, when in reality the already had but still I manually assigned artwork to them via iTunes but they still wont show up in the finder.

2) my video files, MP4 and MKV`s were default assigned to quicktime, but I installed VLC and assigned that as default player to them, but they still would show up quicktime icon.Though double clicking would open VLC.

After see thing those problems, I tried to fix.
So the above mentioned commands, I ran them, it did update all the icons of the assigned apps. e.g. if i assigned MP4 to open with VLC, it showed VLC icon instead of quicktime.

But NOW, if I again change the default app, it wont update the icon. It`ll stick to VLC icon but open with the new default assigned app.

I tried in safe mode, tried with a new user account and also just finished reinstalling yosemite, its still there.

And now i have an additional problem. I have an external display connected via HDMI. It has started to flick on its own after irregular intervals.

I`m going crazy here.

Please refer to the screenshot. Hope they make sense.

As you can see in the screen shot, all the icons are no identical.
