The build is using the “dynamic OpenGL switching” Qt backend, which afair first tries ANGLE, then OpenGL directly, then software rendering.
If the OpenGL setup of your system is borked, that will still result in ugly problems though.
The cure in that case is to run Qt Creator with QT_OPENGL=software
