I had the same issue before, my textures looked like a green brown mess and never cleared up. If you uninstall england and norway, see if it cleares up. I have OLC Europe installed and and when I only had Global installed I didn't have any problems. My solution was to change the affinity mask to 249. Now everything looks great and I have better performance now and almost never any blurry textures. Try to set your LOD radius to 4.5 or even lower.
Saw you had solved it, nice
