Sharpen filter checkbox for activating does nothing
Activating the checkbox for the sharpen filter in the settings doesn't activate sharpening, I don't know if it does anything at all. activating the checkbox in the "Adjustments and effects" window works though. Using the slider and saving saves the value to the filter settings, so I'm fairly sure it's the same sharpen filter.
This is happening in version 4 (nightly) and 3 rc9.
