Many layout features not working on Windows 10 as VirtualBox guest

  • Many windows layout features are not working for me in Windows 10 running inside VirtualBox:

    • No suggestions are displayed under the address box when I start typing;

    • The toast with URLs is not being displayed when hovering over links;

    • When any sidebar app is clicked (i.e, Whatsapp), the entire browser stops responding to clicks, except for the Opera menu button. Clicking the menu button makes it start responding again.

    Running version 45.0.2552.812 (PGO). On version 42 everything was working (except the sidebar, of course).
    On my Windows 7 machine, everything works fine.

    I have no extensions installed. Actually I just uninstalled completely and reinstalled the browser, and the issue remains.

  • Now I realized I can't even sign in to Sync, because no popup dialogs are working .

  • Turns out it has nothing to do with VirtualBox. Adding -disable-dwm-composition fixes it.

  • Do you have guest additions installed?

  • I have the same problem. Can u pls tell me how to fix it? where do i have to add the command? sorry i'm have just started using opera recently and don't know what to do.

  • Welcome to Opera's forums @Invisiblemanzz!

    You have to create or mod an Opera's shortcut and add this switch in target:
    -disable-dwm-composition

    Path to Opera -disable-dwm-composition
