yes, that's what I mean. It works with xfce, lxde, mate, kde, actually anything that doesn't use openGL compositing as far as I know.

Which probably means that the newest gnome will also not work

well I can't say that for sure. I have a Debian install with gnome 3 and it's the only guest with openGL compositing that I can take a screenshot of inside the guest. however the cursor disappears when mouse integration is disabled.

btw, the simplest workaround for you is to keep mouse integration enabled and 3D but instead of using full screen, just maximize the guest window. you won't lose much screen area and you don't have to worry about hot corners.

Excellent, that actually isn't half bad! Thanks!

I'll post here when I hear anything from either Virtualbox or Unity, or if I come across something that finally sorts things out fully.

well I wouldn't hold my breath.
Unity has been a pain since it came out as far as VMs go.

Hi, did you ever find a fix or work-around for this?

As far as I can tell this is still a problem to be fixed, but not exactly sure by whom (most likely a combination of Unity and Virtualbox).
Anyway, my workaround was to not go full-screen anymore, and to use a faster window manager (ended up with Fluxbox).

This happened to me too when I disabled mouse capture. The mouse cursor outside of virtualbox became stuck in one place (because I disabled it) and the new mouse pointer in virtual box becomes invisible. The best thing to fix this problem is to actually use an external device, such as a pc contoller with analog sticks. So, plug in your pc controller of whatever external device you want first, then download a free program called JoyToKey or something similar ( I would suggest JoyToKey, it works perfectly). Now, open JoyToKey and map your keyboard keys, like w,a,s,d or up, down, left, right and left and right mouse clicks, including middle mouse roll, and mouse movement axis (what you use to move a mouse, I mapped mine on my controller analog sticks to move pointer around) onto your pc controller. Next, open virtualbox (disable capture). This way, at least now you can move the pointer that was stuck initially in one place with your pc controller. So, if you want to use in Unity3d, open Unity3d now. Move your pointer using your external device, try to preview a game you made, and now you can look around using the mouse! Alternatively, disable hardware acceleration in Display options (however this doesn't work if you want to use Unity3d, because the pointer still disappears when hovering over program) It's not letting me paste my tutorial link here, so type 'Fix Invisible / Disappearing Mouse Pointer on VirtualBox Solution, WorkAround' in Youtube.

Just an update, this still doesn't work with Ubuntu 16.04 running whatever gnome-shell version that's on there that's current today.

FWIW, It's really not necessary to announce "something still doesn't work". If something that did work breaks or something that didn't work is fixed, those would be good to know.

About 3D acceleration on OSX, it seems it is still very much "experimental". The main desktop environments it has trouble with are Unity, Gnome3, Cinnamon and now KDE Plasma5. All which use some variation of Compiz. Personally I think it will require a major rewrite on how 3D Acceleration is done with OSX hosts.
