Which version of SDL have you been using here? SDL 1.2 or SDL 2.0? If you were using 1.2, could you please try with 2.0 instead? Support for 1.2 has been removed now.

When I run start a guest machine, its SDL window is moved to that workspace (I never see it); but the machine freezes after displaying that black window. It only starts booting after I switch to the workspace and view the window. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1730101/+subscriptions
