Has anyone successfully run GrADS on a Mac with the M1 or M2 processor? With a lot of help from my sysadmin, I got it built, but the GUI graphics plotting is messed up (sorry for the unscientific description), with only contour labels appearing (without accompanying
contour lines) being one of many seemingly random and show-stopping graphics glitches. Output to pdf via gxprint/printim is unaffected. But it's the interactive aspects of GrADS that make it so useful, so having to use gxprint/printim to see what's actually
plotted is obviously not convenient.</div>
