Bad geometric distortions (waves on lenses when moves) and more blurry edges with latest v1.0.18

Headset: Crystal light

Has anyone else noticed this?

I got this problem with after 1.40.4 update, downloaded from Pimax site. I did full reinstall and returned to 1.40.1 pimax play, but still have same issue. How to revert headset back to 1.0.17 firmware?

These distortions are different on left and right lenses.
