shotcut-20.07.11 fix for blank file dialog/chooser windows
I had problems with all the file|open dialog windows in Shotcut, the
video editing application. I would get an empty window instead of a file
chooser and the application would hang with a GtkDialog error in its
log, followed by other gtk errors.
I am running openbsd 6.8 with fvwm, and had installed shotcut-20.07.11
I was able to fix this by installing the qt5ct package and setting the
environment variable QT_QPA_PLATFORMTHEME to "qt5ct".
