Photoshop CS6: artifacts in rotation

Whenever I rotate a pixel layer in Photoshop CS6 I'm getting a strange blockiness in the resulting image (see attached). Even a slight rotation will cause it, bigger rotation = smaller blocks. The problem also occurs when using Photomerge to make panoramas and some of the source images are rotated during the process.
I've tried turning off 'use graphics processor' but to no avail.
any suggestions welcome

Which interpolation/resampling kernel are you using? (because that kind of looks like nearest neighbor resampling results).

Did you restart Photoshop after turning off the GPU?

Any chance you copied plugins from a previous version of Photoshop?

I am using automatic interpolation. I tried switching to smoother and restarting, same results.
I did restart photoshop after turning off the GPU. same results on all files. It is less obvious on smaller files but still shows up looking at 200%.
I haven't manually copied any plugins across.
