Almost certain that when you did a new install, the latest Intel graphics driver got utilized and that's the fix.
I had the exact same problem with all of the Collection V v.6 this past December. All of the synth plugins actually worked, but the graphics were so mangled (just like your images you uploaded) that I could barely use them.
I went into Device Manager (Windows 7 Pro 64-bit) and elected to update the driver by allowing the system to search online. 30 seconds later, after the update succeeded, everything graphically in the Arturia Collection was fixed.
