Yes. When you rotate the image by anything but a multiple of 90°, there is no one-to-one correspondence between the pixels before the rotation and pixels after. So the pixels "after" are interpolated using the pixels "near" their original theotical position (which straddles several pixels). So there is a slight loss each time, not too visible on the first iteration, but more and more visible as you accumulate iterations.
There is no fix for this, this is a well-known restriction of the bitmap editing. The best you can do is making sure that you are using the "NoHalo" interpolation.
But you shouldn't be needing to do this. If you want to draw lines at multiples of 15° can you can use "constrained angles": click to mark origin, depress Shift to put the brush in "straight line" mode, and then depress "Ctrl" to force the straight line on 15° marks, then move to your target end and click again.
For sharp lines, an even better technique is to create a path with several lines, and then stroke the path in "Line" mode.
