I really don't think this has anything to do with Qt. See below.

So I presume you have a framebuffer device at /dev/fb0. In that case,
you can enable the Buildroot package for the framebuffer tests
(BR2_PACKAGE_FB_TEST_APP) and the run "fb-test".

See how blue matches blue, red matches red, etc.

Can you do this and let us know?
