I now know what causes this: Setting the windows version "higher" than WinXP brings up this error and the trippy colours. Unfortunately I FEEL like LotrO runs smoother on Win7 or Vista settings, though the framerate seems the same. As well, things look better, but that can easily be contributed to some DX-stuff that is not available under XP and which probably causes all the problems in the first place. So: Pretty and cool, but with an error, or clean and safe with XP, it's a tough choice...
