It's been so long since I've encountered this I don't remember how to fix this or if it's possible, basically whats happening is some objects in the GECK won't read their texture paths correctly for whatever reason, which is usually caused by texture mods (in this case Ojo Bueno), and so they (objects in the cell, say a rug) constantly flicker with the textures of other objects near them.
Trying to make a lightweight house mod quick and it's rather difficult to figure out how it looks since about 30% of the objects are having this issue.
