That would be #20033
I guess chatGPT still made a mistake may be? :D

Well, I blame it on the awful full libpng API. libpng has a million ways to fail and few ways to succeed.
Gonna fix it of course.

Was about to open an issue for this after noticing it affected "PSPKVM v0.5.5 Final Release CFW". (Good thing the checklist exists 😄 )
libpng: Ignore benign errors. Should fix #20050

That was quick. 🚀 The icon for PSPKVM appears correctly now.

Okay, I've made a screenshot with PSPHUD. It appearing brighter seems to be correct. Rather, it looks like some PC applications display it incorrectly.

MS Paint displays it correctly though!
Sorry for the confusion. What a way to spend an hour... lol

The PSP incorrectly ignores the gamma setting specified in png image files, while libpng by default (and most other applications) do use the gamma setting.
We should of course follow the PSP behavior.
