4.26.2 Oculus Quest OS splash screen PNG Warning: iCCP: known incorrect sRGB profile

My log is spammed with the following 2 errors on the Quest upon launch. I think it’s due to the OS splash screen. I’m using the Oculus branch of 4.26.2.

Hello,

I have the same problem.
Since I have used the 5.1 engine I have the same logs with the basic VR template Unreal.

I have found a track.

To use ImageMagick to convert any png image in my project.

I try to copy my project into WSL Debian machine and I run that command.

for png in $(find -iname *.png); do convert $png $png.out && rm $png && mv $png.out $png ; done

Unfortunately, it didn’t work.
I’ll continue to try with windows method.

I have tried with imagemagick on Windows.
I created a .bat file with this code in the project folder.

@echo off
echo ImageMagick is fixing libpng warning
for /f "tokens=*" %%i in ('dir/s/b *.png') do magick.exe convert "%%i" -strip "%%i"
pause

Unfortunately, the problem didn’t solve.
