Webkit QFont::setPixelSize: QT 5.5 on Arch linux

[liewjls]

Hi,

I'm running my QT application on Arch linux using QT 5.5. When it is running on my desktop ubuntu linux, it works OK but right after i have cross-compile and run it on my Rasp Pi, it has triggered some warning or error message,

libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
QFont::setPixelSize: Pixel size <= 0 (-1)

QFont::setPixelSize: Pixel size <= 0 (-1)
QFont::setPixelSize: Pixel size <= 0 (-1)
QFont::setPixelSize: Pixel size <= 0 (-1)
QFont::setPixelSize: Pixel size <= 0 (-1)

However, if i recompile with QT 4.8, the "QFont::setPixelSize: Pixel size " doesn't shows on the screen. I had done some googling and searching, I noticed QT 4.8 has the directory of " /opt/Qt/4.8.6-arm/lib/fonts/ " but in my "/opt/Qt/5.5.1-arm-pi3/lib" doesn't have "fonts" directory.

Is there anyone can help me one these warning or errror message please? I would really appreciate if someone can help me as I'm new on QT and arch linux.

I'm bit stuck here, any help please?

I noticed there memory is slowing increasing when I have load the url then I got these error message. Is that something i have missed out?

Many thanks.

Regards,
jenny
