Kind of abandoned this post for two months while working on other things, I hope you can bear with me.
I feel like this is maybe something configurable? The 5V pin on the raspberry which the display draws from is outputting 5V even when the pi is "off". Is this how it's meant to be? It seems to me that simply cutting that power, even momentarily, would allow the screen to properly load next time - and that this is the issue.
If it's indeed a kernel issue (something like the DSI sending a command the screen can't understand?) - Is there a way I can update the specific drivers or firmware that interact with the screen without fully updating my kernel or OS? Switching to Rpi OS isn't an option and I would rather avoid risking issues by wiping and loading the newest ubuntu image.
Thank you!
