(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)
long-standing Konsole bug, fixed in newer versions like the ones in Fedora. some people had success with playing with Line spacing and Margins in Settings/Profiles/Appearance/Misc
Thanks! I will play with those and report back. Also The issue seems to be only happening on my external monitor or a least I had not noticed it on my internal one. The external monitor is the one set to 75% - perhaps I need to change that?.
yes happens with scaling
