That line in the flame texture is only visible on a darker background, just for reference! 🙂
Edit: Also while actually in game, it's more noticeable in motion.
This issue affects any number of candles in my experience. It's similar to the torch flame. Bedrock torches kind of just "pulse" on every now and then before disappearing for a few seconds, before another puff.Â
I would love it if when running fancy graphics in Bedrock, that the Java torch effect with the constant flame and smoke be added.
It's a big immersion factor!
Also, fancy graphics or another option should enable the full Java style torch flame and smoke animation.Â
I think there's a difference for candles as well, not 100% sure.
Yes still an issue. Generally visible against a darker background or night time. Applies to torches and candles.
