Ah good to known, I will keep a note about this env variables to print the info.
Seem like if I used the 3D acceleration, the AA samples is not used and stick to 1, but if I do not enable the 3D acceleration into my VM, I get lie and it tell me I have the requested samples but it is not seen into the rendering. I did try with 4x and 8x samples. I'm a bit confuse about this. *************** VM (Virtual Box with 3D acceleration option) *************** QML debugging is enabled. Only use this in a safe environment.
