Hanging popup some times after loading DICOM files

Sometimes after loading som DICOM files, the popup window showing the text “Processing…” doesn’t disappear unless I close it manually. I don’t know why it happens, and it doesn’t happen every time. Usually it just disppears almost immediately after it appears. But when I look at many different DICOM files in a row, it inevitably happens after a while. I use CRTL+w to close each scene and then go to the DICOM browser to select a different entry in the DICOM browser, click on “Examine” and then “Load”.

The problem is not tied to any specific DICOM files. I’m not able to reproduce it reliably.

Here is a screenshot showing the hanging popup window:

Which Slicer version are you using?

I’m using Slicer 3D nightly version 4.11.0-2019-03-03 r27973 on Linux. I think the problem has occured on all the Slicer versions I have used for several months. I have only used the nightly builds.
