Qt examples fail to run on a discrete NVIDIA GPU
I'm on Arch Linux (GNOME 3.24, Wayland) using a workstation both with an integrated (Intel) and a discrete NVIDIA GPU. I use Bumblebee to run applications on the discrete GPU. Even though VTK 7.1.1 and 8.0 rc2 examples (excluding Qt) run on both GPUs, Qt (version 5.9) examples fail to start on the discrete GPU.
For instance, running the qtevents
example on the discrete GPU using $ optirun ./qtevents
fails with

fails here with Missing GL version
. This happens both with VTK 7.1.1 and one of the latest commits (6ee6af0c).
Trying to run a simple Qt based test application I wrote fails with the following message:
[VGL] ERROR: in TempContext--
