This is fixed in bionic with 5.2.2-3 version (69989.patch). I don't plan to fix artful, that will go EOL soon, and has an older vbox. If somebody wants to test a fix, feel free to do it.
In the meanwhile I uploaded the fix in my ppa https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/virtualbox-ppa ** Changed in: virtualbox (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1724810 Title: 17.10/wayland causing flashes in virtualbox Status in GNOME Shell: Confirmed Status in gnome-shell package in Ubuntu: Fix Released Status in virtualbox package in Ubuntu: Fix Released Status in gnome-shell source package in Artful: Triaged Bug description: Hi, just as a quick response: I've installed the new 17.10 Desktop for testing in a virtual machine (VirtualBox 5.1.20 running on MacOS), and while it installed smoothly and booted instantly, there's a problem with the graphics (probably related to wayland): Especially when moving the mouse or starting new programs the screen flashes white every few seconds or sometimes shows just a blank grey screen for about a second. Not suited for regular work. But I have no clue which component precisely is causing that problem. regards To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1724810/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
