So I install a brand new ubuntu 18.04 in virtual box. I installed both host extensions and guest additions. My host system in a windows 10. I activated the 3D acceleration in my VM settings.

when I ask ubuntu, I thinks it answers that I do have 3D acceleration :

```
glxinfo | grep direct
direct rendering: Yes

```

The thing is, gnome 3 is not running smooth at all. No fancy effect or anything. Any lead is welcome, from the good combination of versions to maybe just tell my guest ubuntu how to use the 3D acceleration ?
