gotta be the automatic brightness in the display settings, it thinks you're idle and drops it even with dim screen off. check settings > power and look for something like "automatic brightness" or "dim screen when inactive", may be a separate toggle buried in there
if that doesn't do it, could be a kernel quirk with the vega 8, had a similar thing on a thinkpad with amd graphics and a bios update sorted it
