Fix for Linux GUI rendering problem?

I'm experiencing a problem with the 2015b GUI rendering, where I periodically get ghost text boxes that become stuck (see attached). I must restart MATLAB to get them to disappear, but given enough time, new boxes will appear during my editing, and persist until I close MATLAB.

Perhaps related, perhaps not: The quick help text box (the one that appears when you hover over an orange-squiggled bit of code in the editor), does not show any text, and instead shows solid gray.

I'm running Debian 8.2 w/Gnome Wayland, utilizing the default Intel video driver (Lenovo T450s) that was installed when I installed the OS.

Was this problem ever solved? I have the same problem on centos 7.

The bit about the quick text box showing solid has been reported a few times to be related to Unity, that it goes away if Unity is turned off.

I've seen some of those posts as well. I've logged out of my session and tried logging-in using Gnome, Gnome Classic, and Gnome Wayland, all with the same result. I was under the impression Unity was disabled with (at least) Classic.

Do you know if this is indeed the case?

Sorry, I do not know anything about Unity other than this narrow context.
