Unity launcher feels sluggish in VM
Not sure if it is partially a rendering issue or just that it feels like it is searching all the time - either way it is less than ideal. I feel like something needs to happen to speed it up regardless. I wish I understood Unity better or I might try changing its rending options when the app menu in the corner opens. I know in XFCE and compton I can easily change how things render and the borders of popout menus even.
I might check dconf later and see about tweaking some settings there, as I don't think there are any available unity tweaks in the UI to help speed it up, but I could be wrong.
