Ok thanks. I hesitated to report that, because on one side this is a purely cosmetic issue, but on the other side Desktop-Cube is also a hugely cosmetic extension 😆
All this to say thanks for looking at this but no pressure !

Hi there! Thanks for the report. Once I find the time, I'll look into this. However, I am pretty sure that this is rather a texture-filtering issue than missing anti-aliasing. Super-sampling could help, but better texture filtering would be a much cheaper solution.

However, I am not sure if this can be changed easily. Mutter (or Clutter) seems to do some "intelligent" stuff here: If you look closely, the aliasing disappears at a certain point if a window is rotated out-of-view gradually. The windows which are facing the viewer seem to use nearest-neighbor filtering and if they are rotated a certain amount, they switch to bi- or trilinear filtering. Ideally, they should use anisotropic filtering, but I do not know if that is supported by Clutter.
