InDesign 2018 as soon as its opened the CC Library panel pops up and starts flickering. If you try to do anything in ID it relocates the pointer to the library every few seconds. If you switch to a different program or browser other than ID it takes you back to ID within seconds to the library.
I've tried closing the panel but it just opens up again. I've restarted my machine a few times. Its always the same. It makes it pretty much unusable.

I am having the same problem, and my regular InDesign libraries cause ID 2017 and 2018 to crash. I've resorted to opening ID 2015 just to create a new library.
