They're not super common, but I don't think they're super rare either. It means the gas giant is almost on the cusp of being categorized as a brown dwarf instead. It's generating heat via gravitational collapse, like a brown dwarf, but isn't quite up to that scale. I don't have any numbers on it though.
If the stellar forge handles it realistically, then we should be able to find these in the EDSM data by looking for gas giants within a certain temperature range. The red glow is effectively "black body radiation" (a fancy way of saying "heat glow").
Do you have data on this planet? Specifically temperature, radius, mass, etc?

That's not the phenomenom in case here. The glow is something I don't recall seeing before.
Yep, that makes perfect sense. It's a very high mass planet, and the gravitational collapse is keeping it pretty hot. At around 1,000 K, it should glow red. Check out the chart here:

(copied below)
1,000 K - Red
1,500 K - Reddish orange
2,000 K - Yellowish orange
2,800 K - Yellow
3,500 K - Yellowish white
4,500 K - Warm white
5,500 K - White
And this, from the black body radiation wikipedia page:

Some additional info.. In my copy of the EDSM data, I have over 45,000 gas giants that are at least 1,000 K in temperature, with the hottest being over 13,000 K. In that range, it should be lit up a brilliant blue, like a small blue star in the A/B class range. Somehow I doubt the game is rendering the right color temperature at those high temps. I suspect these ridiculously hot planets are due to proximity to the star, but haven't checked. The game is probably only looking at the heat coming from its gravitation when deciding how to render it, which will make them mostly dim-red as long as they're smaller than brown dwarfs, but still large enough to have a visible heat emission.
Here are the hottest 25 in the list:
