    Change FBC idle mode back to default
    
    Use the "immediate idle" mode for FBC.  Rather than waiting for the current
    compression pass to finish before signalling to the CPU that it's idle, this
    mode should stop any current compression pass and tell the CPU that the GPU is
    idle right away.
    
    Seems to fix #13326.
