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.
libpng is more stringent about checking ICC profiles than previous versions. In Qt, if you use certain formats of PNG images, you may get a warning ‘libpng warning: iCCP: known incorrect sRGB profile’, though this will not affect the compilation.
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.
