Blocky/Low Res Icons in start menu

[Scottland]

This is what my start menu is looking like. If you look at the icon's some of them are degraded, and low res.

They never used to be like this, and changing the IconPackager theme doesn't make the problem go away.

I've tried rebuilding my icon cache, but that doesn't solve it either.

Anyone know what causes this?

All my icons in explorer etc are fine...

The problem has only appeared recently, and it was the same one other visual styles I've used.

I will create another user though to see if the problem is the same on that.

Cheers
