I got a Raspberry Pi 3 yesterday and installed it with the default Raspbian OS (a.k.a. Debian) and tested the
glxgears program to see how good (or bad) the OpenGL/3D support was.
For some reasons, I was thinking that the motherboard included some form of GPU when in fact it generates all the 3D rendering using the CPU and its NEON coprocessor (equivalent of SIMD on an Intel.) Don't get me wrong, NEON is great, but compared to a hardware GPU... you know...
glxgears barely makes it in 30 FPS at the default size, but the colors are all wrong. The large gear flashes between red and orange. I've made a video on YouTube.com to show what I'm talking about (poor quality, but I think we can see the flashing going on):
What I'm wondering is: Is this the expected results as of Mar 12, 2018?
I read that the OpenGL driver is still being worked on, but I did not expect that something as "basic" as the glxgear would not be working better yet. (i.e. why would you release such a version to the public?)
