I recently tried KDE plasma after 5.12 update and it is running smooth.
However I am experiencing two problems with virtualbox.
1. Virtualbox applications do not start unless QT_QPA_PLATFORM is set to xcb.
Under plasma wayland session it is set to wayland.
2. When a VM is launched, if it is maximized with Host-F, it loses all
keyboard/mouse interaction and has to be killed from the plasma session.
Anybody has seen this? Should I report it upstream?
kde plasma 5.12.0
