Just stating here that it currently affects 18.04 and 19.04 as guests on Vbox 6 on Macos (Mac Pro 2018).
Flickering white screen happens only with Wayland and not X. X works fine. Guest additions installed as well. VBox extensions installed as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724810 Title: 17.10/wayland causing flashes in virtualbox To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1724810/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
