Force re-rendering of smart filters

When working with smart objects and filters, Photoshop renders the layer data produced by the filter once and then uses the result for further processing. However, for some geometric filters (e.g. Polar Coordinates or Perspective Warp), the results of the filter pass would be different, given a different x/y displacement or canvas size. Sometimes results are not rendered at all outside the current canvas, so when moving the layer data, artefacts or empty areas might come into view.

Is there some prefered way (e.g. a shortcut or a script command) to force re-render of all or selected smart filters in a smart object layer to fill those areas with properly filtered data?

Actions and scripting

Can you give a sequence of actions and a screenshot explaining your problem using the example of PolarCoordinates? I cannot reproduce the bug.

In order to recalculate the filter, it is enough to turn it off and on.

Code for one filter with index 1.

var d = new ActionDescriptor();
var r = new ActionReference();
r.putIndex(stringIDToTypeID("filterFX"), 1);
r.putEnumerated(stringIDToTypeID("layer"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));
d.putReference(stringIDToTypeID("null"), r);
executeAction(stringIDToTypeID("hide"), d, DialogModes.NO);
executeAction(stringIDToTypeID("show"), d, DialogModes.NO);

I did not want to imply, that there was a bug in PolarCoordinates, I think this is expected behavior. The source of the problem might have even been with the rendering of another geometric smart filter in the processing chain. I've attached a visualization of the problem with the Perspective Warp filter. It shows

1) The original application of the warp.

2) Changing the x/y translation and thereby moving the layer data towards the top left corner. Note the "empty", "unrendered" area on the bottom right.

3) Result after turing the filter off and on again. This solution seems to work for a single filter only. Turning the "Smart Filters" entry off and on again didn't have an effect.
I was hoping for some kind of built in "re-render" or "refresh" command, but solving it with a script using the "off/on" approach works as well.

Does this help?

// force redraw of smart filters;
// 2021, use it at your own risk;
if (app.documents.length > 0) {
var theSmartObjects = collectFilteredSmartObjects ();
for (var m = 0; m < theSmartObjects.length; m++) {
    var desc10 = new ActionDescriptor();
		var ref6 = new ActionReference();
		ref6.putIdentifier( charIDToTypeID( "Lyr " ), theSmartObjects[m][1] );
    desc10.putReference( charIDToTypeID( "null" ), ref6 );
    desc10.putEnumerated(charIDToTypeID( "FTcs" ), charIDToTypeID( "QCSt" ), charIDToTypeID( "Qcsa" ));
    var idOfst = charIDToTypeID( "Ofst" );
        var desc11 = new ActionDescriptor();
        var idPxl = charIDToTypeID( "#Pxl" );
        desc11.putUnitDouble( charIDToTypeID( "Hrzn" ), idPxl, 0 );
        desc11.putUnitDouble( charIDToTypeID( "Vrtc" ), idPxl, 0 );
    desc10.putObject( idOfst, idOfst, desc11 );
executeAction( charIDToTypeID( "Trnf" ), desc10, DialogModes.NO );
};
};

cmd-T, enter would seem like an option, doubleclicking any Smart Filter and hitting OK another.

Thank you for the answer. I should have been more clear. What you suggest, is exactly what I'm doing right now. However, I would like to to just re-render all (selected) layers without revisiting any input or preview windows.
