I have two displays. Monitor 1 is 60hz 2650 x 1440
Monitor 2 is actually a drawing tablet, 1920 x 1080.
I've had the tablet for a year and the monitor since I got my computer in 2017, but lately, I don't know if it was from an update or from when Dad and I cloned the HDD onto an SSD, but any time I switch displays back to the main monitor after using to the tablet, all of my desktop icons are crammed into the top left of the main monitor.
Note: This did not always happen, I just tried downloading the latest drivers for the tablet and my computer stays up to date automatically.
I'm aware that icons move themselves when the resolution changes, mine did too at one point, but now it they don't return to their relative positions when I switch back to the monitor.
