Qt5.6 application : red and blue colors swapped

[florin]

Hello,

I recently compiled qt5.6 with the configuration bellow. I am having a simple application that is using qtwebkit to display an url page on a lcd display. The webpages displayed have red and blue colors swapped. The qt engine is using the linux framebuffer.
If I set the number of bits per pixel to 16, the webpages are properly displayed.
echo 16 > /sys/class/graphics/fb0/bits_per_pixel

The number of bits per pixel by default is 24 and I would like to use this value instead of 16.
I have also attached the framebuffer information bellow.

Hi and welcome to devnet,

Since you are using an unreleased version of Qt and hitting something that's probably influenced by the internals of Qt. I'd recommend posting your question on the interest mailing list You'll find there Qt's developers/maintainers (this forum is more user oriented)
