I have never seen that before, but it looks like it is the TV. Someone else with a similar problem
https://forums.linuxmint.com/viewtopic.php?t=355280 big cursor on TV (but ok on regular monitor) Although the desktop environment (DE) seems to have an effect.
pop_os uses gnome you could see if you can install some other DE
or
Use a 'live' usb to boot and see if there is any difference. You could try the knoppix iso KDE , has Gimp installed and runs on just about anything. Not for a permanent installation, just a try-and-see.
I have tried a few possibilities here, Changing the Gimp resolution setting / Changing the computer screen size / Changing the system cursor size. To no avail.
Guessing it is that HDMI connection to the TV rather than a Gimp issue.
I do not know, maybe someone will come up with a solution
Edit: Just been looking at the Minisforum HX90 specs (very nice) . It has 'display' ports and HDMI connections. I assume HDMI is being used. Any settings in the bios for these ?
