Camera randomly moves

Since 1.14 release camera is randomly moving around on my PC. This is not happening in older versions and it isn't fixed in 1.14.1 preleases. I think it's returning to random positions it had before.

Video below. Sorry for 30FPS and LQ at all, I messed up OBS settings. It was 14MB and it didn't fit as attachment, so I uploaded it to YouTube.
