I'm running macOS High Sierra 10.13.3 on a MacBook Pro Retina 13-inch. The white box below appears and even a restart can't get it to go away. What can I do? It's on the MacBook itself. The two external monitors I run stay clear and fine.
MacBook Pro with Retina display, macOS High Sierra (10.13.3), null
Thank you for your fast response, macjack. Just today the box came back and I got to check these steps, and unfortunately neither worked. "Go to folder" did work when I took out the period between "center.ui" in this command: ~/Library/Preferences/com.apple.notificationcenter.ui.plist
I moved the .plist folder to trash
I emptied the trash
The box is still there.
Back on March 2, when I wrote the post above, the blank notification box disappeared when I opened another app, Sametime.
Opening Sametime today and the blank notification box doesn't disappear.

I thank you for alerting me this is a notification box. I get more frequent notifications from Slack -- and in about that position--than Sametime. So I will go to Slack support. Appreciate your sleuthing abilities.
It looks like a blank Notification. Try turning on "Do not Disturb" in System Preferences > Notifications and see if it disappears.
If that doesn't work try deleting the Notifications plist:
From your Finder "Go" menu > "Go to folder" and enter
~/Library/Preferences/com.apple.notificationcenter.ui.plist
Press Go.
Delete the plist file.
Yes, the period was a typo. My bad.
The box seems like it is associated with Sometime. I can't help you with that as I've never used it. You might try their support site for help.
A white box reappears and stays stuck on my MacBook Pro screen
