ubuntu studio – Mouse Pointer Fails To Load

95% of the time my mouse pointer (arrow, hand, whatever the context is) is not loaded and instead I get a relatively large box with vertical lines in it. Clearly the background for the pointer image. Every now and then somehow the pointer does load and works fine. But if I have to reboot for some reason, it almost certainly will not load on reboot. Some solutions suggest reloading the entire desktop. That is very disruptive and doesn’t work anyway.

Is there a way to reload just the mouse pointer image/behavior/applet or whatever it is? I noticed that this pointer has a drop shadow–a recent innovation. Is there a way to set my desktop to load an older version of the pointer that might be more reliable? I have ubuntu studio 20.04 on a T60.
