--- Comment #2 from Christoph Feck <cf...@kde.org> ---
It looks like the newer Qt version in Neon doesn't correctly check for
supported OpenGL version. It is also possible that Qt now requires at least
OpenGL 2. Please report this issue directly to Qt developers via
https://bugreports.qt.io/ referencing the lines I pasted below.
