Summary	08089: crt-geom-deluxe renders halation effect in front of the shadow mask
Description	As seen in the Mario picture with exaggerated values, the halation effect (that "glow" around the graphics) is being rendered in front of the shadow mask that the shader comes with, instead of behind as would happen on an actual CRT. This makes things look blurrier and harder on the eyes than intended.
Steps To Reproduce	-Load any game which preferably has a black background (from bosco to nes galaxian) -Open the slider settings -Turn "Halation amplitude" and "Halation blur width" all the way up
Additional Information	Might be the reason why even the minimum possible value for "Halation amplitude" (0.01) doesn't feel subtle enough.

No.19284 ICEknight Tester Sep 26, 2021, 04:18	I've added an (overexposed, for clarity) example taken from real hardware (PAL NES Road Fighter), where the halation effect can be seen behind the CRT's shadow mask.
No.19287 Tafoid Administrator Sep 26, 2021, 18:41	As I understand this crt-geom-deluxe is a shader written by a third party and we cannot do much to maintain it. You'll have to contact the original author for further support (cgwg)
