Qt example "textures" cannot render images on QNX x86 virtual machine

Hi Everyone,
I built and deployed the Qt4.8 example “textures”, and ran it on QNX6.5.0 x86 virtual machine, but it only left black spaces where supposed to be images. (The Qt version I built on Ubuntu20.04 virtual machine with “-egl -opengl es2” options.)
Does anyone know how to configure on the Qt side or the QNX side to make this example run normally? Thank you in advance!

I really don’t have any idea but I’m wondering if you need hardware acceleration support that isn’t available on QNX 6.5? There was some support but as I recall it was very specific hardware.
