OS X: Compiz in OpenSolaris guest causes misbehaviour with Spaces.app

[Calum Benson]

When running compiz in my OpenSolaris guest, the guest window refuses to stay on the OS X Space (virtual workspace) on which I placed it.

When switching between Spaces, the guest window keeps re-appearing on Space 1, leaving a black space behind on the Space it's supposed to be on. This seems to be easier to reproduce if the guest is running in fullscreen mode, although it also happens in windowed mode.

This does not happen when I disable compiz in the guest and use metacity instead, even while 3D acceleration is still enabled for the guest machine.

I am also seeing this on 2.2.4

This also happens in Ubuntu 9.04.

Any time the client switches screen modes it moves to workspace 1 all on its own.

That's seriously annoying.

Why has it been two months with no action on this bug?

This also happens with a Windows 7 guest. Please remove Compiz and OpenSolaris from the summary and component of this issue.

In fact, this problem even happens even before I start running any guest VM. Just the initial VirtualBox Manager window exhibits this bug. Here is how to reproduce, running any version of Mountain Lion (Mac OS X 10.8.*), and any recent version of VirtualBox (4.2.16 and at least the four previous versions):

1. Go to the Expose view (e.g. 3 fingers swipe upward) and make sure there are at least 3 desktops.

2. Go to Desktop 3 and open VirtualBox.

3. In the dock, control-click the VirtualBox icon and select Options > Assign To This Desktop.

4. Close VirtualBox and go to Desktop 1.

5. Open VirtualBox. VirtualBox opens in a new Desktop which is inserted between Desktop 1 and what was previously Desktop 2. What was previously Desktop 2 now becomes Desktop 3.

A similar problem occurs with a guest VM window of any kind.

Please reopen if still relevant with a recent VirtualBox release.
