I want to display a symbol at the top right of one or both of my screens, similar to the lightning bolt symbol raspberry pi OS uses to indicate lack of power, when certain conditions are met.
I’m pretty sure i could cobble a bash script together to decide when to do it, but it’s the actual displaying of the symbol i’m not sure where to start on. It would need to appear on top of anything else that may be on the screen at the time
Everything i have tried googling returns irrelevant results

What you are looking for is some kind of on screen display overlay.
I found this, see if it can be of any use : https://github.com/vascofazza/Retropie-open-OSD

Maybe write it as an GNOME or KDE plugin?
