Forcing X11/XWayland with PYOPENGL_PLATFORM=x11 curabydago works it seems.

Hi @lissyx ,

I remember adding some stuff regarding Wayland users : https://github.com/dagoma3d/CuraByDagoma/commit/b099cc7a336aacbee34184b219a62e02b4fd15c8

Seems it is not enough anymore, will force the PYOPENGL_PLAFORM as you mentioned. Thanks !
