Oh awesome, it's the dev behind Redshift 3DS Thank you Sono.
Didn't know the 3D mode brightness increase would mean it's actually double the standard value. Sounds like alot. But that definitely matches the situation.
Any idea how I could resolve this or even find out which file (I guess it's some system file?) is messing with the gsp module?
If I change the unofficial Luma boot.firm with the official Luma 11 boot.firm (and boot.3dsx), the problem goes away (at least the screen brightness menu shows 142 instead of 285). The flicker is vastly reduced and fades quicker as well.
I was "hoping" the flickering is simply due to the display having to work too hard because of wrong settings and that I better resolve this ASAP to prevent excessive wear. Seems like 285 isn't as excessive as I thought?
Cheers
Hm.. that's neat info. So the gsp module is responsible for brightness changes and something is messing with it.Sounds like gsp gets stuck in 3D mode. In 3D mode the brightness is basically almost perfectly doubled (that's why you see the brightness "pop" when you switch between 3D and 2D mode), and it seems to be getting constantly applied for some reason. It can't really be anything else, especially if you can make it temporarily stick the good value that's clearly a new3DS gsp behavior with the brightness weirdness, and your symptoms match exactly.
tl;dr: something patches gsp in a way which makes it get stuck in 3D brightness without actually turning up on the 3D slider.

The display is an official Nintendo display. IIRC the vignetting you're describing is typical for dying screens that are at the end of their lives, right?. Mine actually has not that many hours for its age and looks absolutely pristine (in terms of the LCD itself). No dying pixels, uniform backlight illumination, no vignetting.As for the display flickering, is it a replacement display, or Nintendo original?
If it's original, does the IPS display have some weird vignette pattern around the sides and edges? Especially the "shape" of the flicker you're seeing in the corner.

That's interesting. I've never noticed the flicker before.. Are you saying this has been the case forever and the flicker was always there? I'll try booting without a custom boot splash as soon as I come home.The flicker is caused by Luma's screen init in combination with a boot splashscreen. Known issue.
