It is interesting to note that the default environment for this project is with a solid black sky and a very high glow setting.
This is our world environment:

[gd_resource type="Environment" format=2]

[resource]

background_mode = 1
ambient_light_energy = 0.0
ambient_light_sky_contribution = 0.0
tonemap_mode = 2
auto_exposure_enabled = true
auto_exposure_scale = 0.5
auto_exposure_min_luma = 2.0
auto_exposure_max_luma = 10.0
auto_exposure_speed = 10.0
glow_enabled = true
glow_levels/1 = true
glow_levels/2 = true
glow_levels/4 = true
glow_levels/6 = true
glow_levels/7 = true
glow_intensity = 0.1
glow_blend_mode = 1
glow_hdr_threshold = 2.5
glow_bicubic_upscale = true

Definitely a feature, it looks awesome :P

[akien-mga]

Did you figure out a way to reproduce this?

[QbieShay]

Unfortunately no. Did not observe this again, but I also haven't used that world environment settings in a while.

I think we can close this for now and reopen / open a new issue if we figure out a way to reproduce it.
