Public bug reported: Thought I'd post it here in case there's an obvious fix. In Ubuntu budgie, QT apps such as VLC, VirtualBox and others take 20+ seconds (or a long time) to open.
The issue is described here: https://discourse.ubuntubudgie.org/t/slow-application-startup/2596/8 https://askubuntu.com/questions/1184774/some-applications-on-ubuntu-19-10-very-slow-to-start/1189599#1189599 It seems to be some issue with qt4 and qt5 library implementation in Budgie (and possibly other Gnome based distros at the moment), as apt purging 'qt5-gtk2-platformtheme' fixes the problem as described in the Ubuntu Budgie discourse above (but it removes the GTK2 theming of QT apps). Adding an environment variable of: export QT_STYLE_OVERRIDE=cleanlooks also makes the QT apps start quickly but removes GTK theming (though, strangely, if manually selecting the GTK2 theme option in the VLC preferences, it works fine and VLC happily starts up fast, in (milli)seconds). Using qt4-qtconfig or qt5ct packages does not seem to fix the problem, in that the QT apps still start slowly, and those apps themselves also take 20+ seconds to start.
