[Gambas-user] "Cannot find EGLConfig, returning null config"

[Ru Vuott]

Hello,

a member of italian Gambas forum wrote that whenever he starts a program from the IDE in console appears this message:


Cannot find EGLConfig, returning null config
Unable to find an X11 visual which matches EGL config 0
Could not initialize OpenGL for RasterGLSurface, reverting to RasterSurface.

He would like to know what it means.

Here his system:
