Using the nvidia-wayland session, when systemsettings is opened no UI is rendered, an empty window is shown. This also happens when opening any other KCM.

Opening in console reports the following error (several times):

qt.qpa.wayland: Could not create EGL surface (EGL error 0x3008)

STEPS TO REPRODUCE
1. Login into wayland with nvidia hardware
2. Open systemsettings5 or any other kcm
3. No UI is rendered

OBSERVED RESULT

Empty window

EXPECTED RESULT

system settings

Issue no longer happens with the update 1.1.3 to egl-wayland. I can open individual KCMs plus the systemsettings5 window.

If that's the case, I suspect https://github.com/NVIDIA/egl-wayland/commit/547055cb58690515077bd9f02b1325ed677650c1 might have been the fix. With that change we now correctly report whether EGL images are Y-inverted or not.
