Issue with screen dimming

I am having a very odd issue with Fedora 44. I have two computers and switch between them using a KVM switch. For some reason, three days ago, I’ve had an issue where if I switch between them after about 30 minutes, the F44 one will be very dim, and when I select the Brightness and Color option from the lower right, the brightness bar will be absent. What’s stranger is this only happens on one of the two profiles I have on the F44 machine, and it can be temporarily fixed by logging out or rebooting. It isn’t the monitor since the monitor is set to 100% brightness on its own internal settings, and is too ancient to be controlled by the desktop anyway. I’ve run every update I could find on this discussion board to no avail.
