Massive Texture Bug in Haukke Manor

Playing on the new dx11 client, the default 'maxium' setting results in this huge graphical bug on the floors in the Haukke Manor group instance:

This happens at a certain camera angle, but is large and noticeable enough. In the 'Maximum' setting, even slowly going through and lowering all options to lowest settings and/or turning off all options available, the glitch persists.

However, changing to any other default setting will remove this bug. Perhaps some hidden setting in the Maximum default setup causes it.
