Rotation bug in KLCK 3.37b900320

All my objects on my KLCK Lockscreen turns 90 degrees when I tilt my phone without me wanting them to do this. This makes everything get scrambled and it even makes some of my background objects glitch so they won't go back to normal unless I turn off the screen and then on again.

In version 3.30 (which I reverted back to) this does not happen. So is this a bug or is it an option to be set somewhere?

I'm attaching four screenshots, one of how it looks normally and three different states of glitched.
