Description
I'm using qutebrowser as my web browser which is based on WebEngine. After upgrade of Qt to 6.9.0 one of my machines with NVIDIA Fermi GPU (legacy 390xx driver) stopped showing any web page content. It appears WebEngine fails to find correct display configuration as neither GBM nor Vulkan is supported by this driver. However Vulkan appears to be forced anyway?
