    Description

      Starting with Qt 5.5, using the Qt5 interface of VLC, three quarters of the video is cropped and thus black.

      This happens only if the interface is integrated with the video (which is the default btw).

      A git bisect lead me to commit "QtWidgets: don't set Qt::WA_OutsideWSRange for 0-sized non-windows" 37f326297d45564298a2c8cb1958a81b858de57c (qtbase/5.5, 13.3.2015) https://codereview.qt-project.org/#/c/108203/ . If reverted, everything is back to normal and works. This change was introduced as a fix for QTBUG-42727.
