Good afternoon Lemage and thank you for posting on the Final Fantasy XIV Technical Support Forums.

When exactly did this start happening? Did anything change/update on your PC that coincides with this? Is this accompanied by any other glitches or errors?

Do you have a screenshot of the corrupted textures?

Can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
