When I enabled the layers.offmainthreadcomposition.enabled preference and restarted Firefox, my browser control buttons (minimize, maximize, close) are invisible with a lightweight browser theme applied. They still take up the space that they should, and clicking in the spaces where they should be still performs the correct actions, I just can't see the buttons.

The buttons show up if I disable the lightweight theme and go back to the default one.

This should have been fixed by one of Matt's patches (bug 980642), please reopen if still present!
