(Solved) by going to a one display only setup, needed the 2nd monitor for other things.

What causes spurious random lines between rows of characters in Konsole or other terminal emulators? The lines go away if one simply moves the window, but as soon as one begins sending characters to the tty they randomly come back 2-5 lines on the screen in random locations. Debian 12, 2 screens, One at 100%, the other at 75% (I think - I don’t seem to be able to open display settings right now)

Display buffer related bugs seems like the most likely reason.

Fractional scaling of your display?

The larger monitor is at 75%, the smaller laptop builtin is at 100%. I rebooted and now I am able to run Display Configuration again.

Well, my 2nd monitor was better served in another location (allowed me to move that monitor to my AppleIIc+ for a color display vs. the green screen 9") so now that I am back on only the internal monitor for the laptop and that is 100% I should not see the ghost lines any more.
