Undervolting causes GPU reset only after resuming from sleep during heavy gaming.
Brief summary of the problem:
On a fresh boot\reboot everything works fine while undervolting.
After returning from sleep mode when playing a demanding games the GPU Rests.
After a GPU reset and resetting sddm with systemctl from a different tty and returning to the desktop applying the same undervolt works fine and the GPU does not reset.
Reducing the undervolt causes the GPU reset to happen much later.
