Weird texture problem

Suddenly got this texture problem with the default C172:

It appears, it only affects this plane, and only the default textures.
Any fixes?

EDIT:
NVM, some textures had gone missing from the root Texture folder, fixed it now
Leaving the topic for the future, if anyone else encounters this problem
