I've looked around but can't find the solution to the following problem: Why is text so ugly in smooth shaded graphics (ContourPlot, etc.)? Here's an illustration:

data = RandomReal[{0, 1}, {50, 2}];
{DensityHistogram[data, PlotLabel -> Style["Label 12345", 20], 
  PlotRange -> {{0, 1}, {0, 1}}, PlotRangePadding -> 0], 
 SmoothDensityHistogram[data, PlotLabel -> Style["Label 12345", 20], 
  PlotRange -> {{0, 1}, {0, 1}}, PlotRangePadding -> 0]}

This is what I get on my system (Mathematica 12.1, Windows 10): The image magnification distorts the difference, but you can see that the text in the left image is smooth and antialiased, while the text in the right image is jagged and ugly.

Note that in Preferences, I've set Appearance/Graphics/Antialising quality to "highest." I realize that can save the image using a high ImageResolution value. But is there any option that I can set to get nice-looking text in these kinds of graphics in my notebook?

Thank you,

Mark
