Tutorial 8 not working in OpenGL

The tutorial 8 (tessellation) doesn't render correctly when using the OpenGL backend, neither on Windows nor on Mac. It works fine with other backends.

On Windows: most tiles are not visible, and some of them randomly appear and disappear soon after. Windows 11 21H2 / Visual Studio 2022 Release x64 / CMake 3.21.3 AMD Radeon RX 6600 XT / driver version 30.0.14023.1009

This could be AMD driver bug. This tutorial works properly in OpenGL mode on Nvidia, Intel, M1, Android ARM GPUs

We tested this on AMD Radeon 6800m (31.0.12019.15004) it works fine. Can you try to update the drivers and retest?
