it's normal to slightly adjust the distortion by changing the "w" value. For example, when rotating by 90 degrees, you should write 0.71 in the rotation line, and to correct the distortion, you should also write 0.71 for "w".
Rotations with larger values lead to greater distortions, which are already difficult to correct.
