V 12.1 under Windows 10 shows additional space above and below BarChart3D compared to V 12 with the same code.

I want to put a label over it, but the space where the bars always stop and the label with V 12.1 is too big. This is not the case in V12. All on the same PC.

I've tried different ways to put the label on, and yet the empty space doesn't shrink. I tried Labeled also and Grid. Also tried to add ImageMargins -> 0, ImagePadding -> 0 as an option to BarChart3D Command, but that had no effect on reducing the space above and below.

Here is the one I'm using now.

dataForChart = {{0.8, 0, 0, 99.2}, {14.285, 0, 0, 100}, 
   {28.571, 0, 14.285, 57.1428}, {0, 0, 0, 100}, {28.571,0, 14.2857, 57.142857}, 
   {28.5714,0, 0, 71.42857}, {57.14285, 0, 14.28571, 28.57142}};

casNames = {
   Text@Style("Rubi", Bold, 10),
   Text@Style("Mathematica", Bold, 10),
   Text@Style("Maple", Bold, 10),
   Text@Style("FriCAS", Bold, 10),
   Text@Style("Giac/Xcas", Bold, 10),
   Text@Style("Sympy", Bold, 10),
   Text@Style("Maxima", Bold, 10)
   };

percentageSolvedByRubi = 99.2;
percentageSolvedByM = 85.714;
percentageSolvedByMaple = 71.4286;
percentageSolvedByFricas = 100.;
percentageSolvedByGiac = 71.4286;
percentageSolvedBySympy = 71.4286;
percentageSolvedByMaxima = 42.8571;

Grid(
 {
  {Text(Style("Antiderivative Grade distribution for each CAS", 20))},
  {Text(Style(
     "Numbers shown on bars are total percentage solved for each CAS",
      10))},
  {
   BarChart3D(
    dataForChart,
    ChartLayout -> "Percentile",
    ChartStyle -> { Red,   
      RGBColor(255/255, 255/255, 0/255), 
      RGBColor(51/255, 51/255, 255/255), 
      RGBColor(50/255, 205/255, 50/255)},
    ChartLabels -> {Placed(casNames, Below ), None},
    ImageSize -> 500,
    FaceGrids -> None,
    Axes -> False,
    ChartBaseStyle -> EdgeForm(None),
    ImageSize -> 400,
    PlotRange -> {0, 110},
    BarSpacing -> 1.4, PlotTheme -> "Classic", Background -> None, 
    Lighting -> None, Method -> {"Canvas" -> None},
    ChartLegends -> {"F", "C", "B", "A"},
    Epilog -> {(*same order as names listed above*)
       Text(
       Style(ToString(Round(percentageSolvedByRubi, 0.01)) <> "%", 
        Bold), Scaled({.14, .6})),
      Text(
       Style(ToString(Round(percentageSolvedByM, 0.01)) <> "%", Bold),
        Scaled({.25, .6})),
      Text(
       Style(ToString(Round(percentageSolvedByMaple, 0.01)) <> "%", 
        Bold), Scaled({.37, .6})),
      Text(
       Style(ToString(Round(percentageSolvedByFricas, 0.01)) <> "%", 
        Bold), Scaled({.48, .6})),
      Text(
       Style(ToString(Round(percentageSolvedByGiac, 0.01)) <> "%", 
        Bold), Scaled({.61, .6})),
      Text(
       Style(ToString(Round(percentageSolvedBySympy, 0.01)) <> "%", 
        Bold), Scaled({.72, .6})),
      Text(
       Style(ToString(Round(percentageSolvedByMaxima, 0.01)) <> "%", 
        Bold), Scaled({.84, .6}))
      }
    )
   }
  }, Frame -> All, Spacings -> {1, 0})

Running the above there

Any suggestions on what to do?

Thanks to a comment from Kglr, I tried this in the cloud. The space is gone, but the numbers in the bar graphs are now shifted compared to the appearance in the notebook. It's all too strange.

To update:

I just found that this could be a mistake! I tried the same code on V 12 on the same PC and this is the output

Is this a mistake?
