stuck help pop-ups

Hi,
This is a minor GUI glitch that may also be OS-specific: sometimes the small windows containing function syntax information that pop up while typing a command get stuck. Right now I'm using R2016a on linux Mint 18, but it also happens in several older matlab distributions and Ubuntu/Mint linux versions.
When such a window gets stuck it blocks whatever happens to be behind it on the main GUI window until I restart the GUI. This usually means that whatever text I may be typing on the command line will be obstructed -- which is annoying. However, the stuck pop up stays put when I resize or move the GUI window around, which is how I deal with this now. The pop-up also doesn't obstruct other windows, including other matlab windows (e.g. the editor or help windows), or other applications I may be running. Which is why it's just a minor annoyance.
Is there any way to clear these stuck pop-ups without killing the entire session? These things don't fail often enough to disable them entirely, but having to restart the GUI just to clear them is obnoxious.
Thanks, Rodrigo

It is a Linux related matter.
The related items I can find at the moment are
I know there were other posts on the topc. I seem to recall some people also related it to Enlightenment

I get the same problem on Windows.

I found a way to replicate the problem reliably
  1. on a folded cell with significant contents, generate a pop up by folding, then mouse-over onto the %% . . . %%
  2. Move the mouse quickly on top of the pop-up
  3. very quickly move the mouse away from the pop-up
  4. select a different file in the editor. Pop up will persist (undesired behaviour)
  5. Then navigate back to original file, and mouse over the original %% . . . %% comment. Voila. Pop-up goes away.
I sent a bug report to TMW just now. Let's see..

I think another way to make this happen is to be at a breakpoint, mouse-over to generate a tool-tip on the breakpoint line, then step-into the code. Editor jumping to a new file sometimes results in stuck pop-up.
