Guidelines and bounding box disappears!

[Mar5E3C]

Illustrator issue. My bounding box and guidelines disappears when I am dragging the guidelines to center the box. How to resolves it? Thanks!

Try and disable Realtime drawing in Preferences > Performance

May have figured it out. Preferences > Performance > turn on GPU Performance

I have the same problem, and answers above didn't work fo me. Bounding box center disapears when pulling a new or existing guide 😞
