Brush outline is way too large

I haven't used Photoshop in a couple of years, and in that time I switched from a Windows computer to a Mac Mini M1 (running macOS Monterey v. 12.4). I have an Asus ProArt monitor that is a few years old and, while it works fine, I cannot change the display settings with Mac commands and Asus doesn't have a driver for M1.  I have the Apple Silicon version of Ps v. 23.4.2.

I started working with Ps again this week and notice that my brushes--both custom painting brushes and picture brushes--display a huge outline compared to the actual size of the mark. I have noticed that cursors for the other tools (e.g., Magic Wand and Eyedropper Tool) are also way large.

I don't think it's a problem with my settings.  For example, I have a brush of my initials that is 70 pixels, the only brush setting applied to it is smoothing, and the outline is about 130 pixels high.  For Preferences > Cursors > Painting Cursors I have tried both Normal Brush Tip and Full Size Brush Tip--the outsized result is the same for both.  I'm using Standard for Other Cursors.  

Is this an Adobe glitch that only applies to Apple Silicon?  I searched this forum but don't find any references to this problem.
