3. Close light table
4. Select same or other images and open light table again: Empty window

OBSERVED RESULT

Comment 2 Maik Qualmann 2018-11-11 16:20:05 UTC

This is a Qt-5.11 bug. Many distributions patched Qt accordingly. However, we have also adjusted digiKam in addition.

You can use the Linux AppImage bundle version instead your distro package. We use Qt 5.9 inside.
