[filter] example not working - mpf 0.80 gmc 4.3

[Needlebat]

Howdy, I have installed all per Anthony's first 3 videos and have Attract mode working as expected. Adding the [filter] example from the GMC reference has no effect:
    [filter]
    filter="virtual_dmd"
    columns=120
    rows=45
    hardness=5
    spacing=2

• There are no error messages producted in the log with logging...=1
• Other examples in the Filter Config Reference also have no effect.
• Creating a Custom Filter with an incorrect filter path throws an appropriate error, so I know the [filter] section is being parsed.
• I have tested with Forward, Mobile, and Compatibility rendering.

Should I expect to see video similar to previous versions? Is there sime additional configuration required in Godot?

Thank you.

Oops! There was a little bug that kept the filter layer hidden even though a filter was configured. I've just pushed the fix to the mpf-gmc repository if you'd like to manually update, otherwise it will be available in the 0.1.3 release soon. Thanks for catching this!

Addition of filter_parent.show() and all works as expected, thank you.
