People/places window blinks

I keep the people/places window open bottom right, of late it blinks, all text goes off, comes back on, often after I have clicked on something or just randomly.

I’m not sure about how it is nowadays, but in the past if you kept people/places open as you traveled it caused mind numbing, soul crushing lag, especially if you had alot of bookmarks. I honestly can’t think of a single reason anyone would leave it open anyway when you can simply right click in space and select the destination bookmark from the drop down menu.
