The demo macro for overlays
https://imagej.nih.gov/ij/macros/examples/CreateOverlay.txtis broken since 1.53f; it works as expected in 1.53e and previously.
The problem is that the text disappears at the roiManager("Set Fill Color", ... call.
Try this in the macro debugger:
run("Blobs (25K)");
roiManager("reset");
setFont("Sanserif", 24);
makeText("This is an overlay", 30, 10);
roiManager("Add", "red");
roiManager("Set Fill Color", "#88000000"); // argb, alpha=0.53
