It doesn’t seem to matter which study I have open but when I’m working with a PDF and excerpting and organising the excerpts, the mind map region of the screen periodically refreshes and it’s extremely annoying. This only started occurring in the latest version.
If other users could either let me know if you are also seeing this or not then I can try to troubleshoot it further. I’m also running a MacBook Pro with the same configuration and this refresh is NOT happening on that machine.
Edit: as a side note this is usually when my mouse cursor (and my eyes) are on the document, not the mind map. So it is refreshing off to the side.
