I recently bought a crappy HP laptop with an AMD dGPU inside.
I have started noticing that whenever Arch Linux (GNOME) turns off the monitor, it goes completely dark, then gets a slight green tint but with no backlight for about 4 seconds, then goes back to black and then loops forever. This only happens when the machine is in standby (everything is running but monitor is turned off). While in suspend & powered off, the monitor has a constant green tint like the one mentionted.
Don’t know if it is a software issue because I did not have anything apart from arch on this machine. I have not found anything about this on the internet.
Is this bad? It doesn’t worry me that much but I would like to know if it’s something that I should be concerned about or not, and I was wondering whether any of you had the same issue / thing.
Will upload video if necessary.
Thanks for your time.

I am using the latest stable AMDGPU drivers with Xorg, kernel 4.13.12-1-ARCH.
Can’t see this being asked anywhere and I don’t think that it’s something to do with overheating because my temps are constantly +50C under threshold, and the fan rarely even spins up. Plus the actual image quality doesn’t ever suffer at all.
I’m pretty sure this is not even an issue, probably giving it more thought than it even deserves, thanks for your response though.
