When using VirtualBox in COSMIC Epoch, I sometimes find my keyboard input still going to VirtualBox and not to other apps after escaping from VirtualBox and switching to another workspace.
This has occurred both with mouse pointer integration enabled and disabled (the latter meaning I have to click inside of the VM/use the right-ctrl key to escape in order to capture/release input). However, when it happens, switching from one to the other seems to work around it for a short time.
