This has happened kinda spontaneously about a week ago, but I gave it no mind. Originally, flower textures, once picked, still showed up and kinda floated with a weird transparent, meshy texture. I thought it was due to a mod I downloaded. Upon playing for a little while today, I noticed that the texture bug had also shown up on dragon wings, and the clothing that Serana wears. I disabled all of the mods I have, and found that it wasn't due to one of them. I also updated my drivers (using an ATI Radeon HD 6670), and found it wasn't caused by that either.

Anyone have a potential fix? Thanks!

(Edit: also, unsure how to attach pictures, otherwise I would. Also, I'd put a link, but I can't post links. Lovely.)

Can you list your mods?

I think I had that issue with a budget video card and only the official DLCs installed, but unless your video card is starting to fail, I don't see how you'd be having it with a 6670 (which should easily handle rendering in Skyrim at medium settings). Was the dragon kind of a blurry gray looking thing?
