It seems like there is some rounding going on with 3D tick label positions. When rotating the plot, the position of the labels move around a bit. This may be intentional to line up pixel values, or it may be an artifact, but the result is "jittering" that looks bad.

This becomes most noticeable in animations:

May be related to #13044? Though there aren't 2D rotations happening here afaik.

TODO: check if the axis labels are also affected
