the 3.1 version is built by myself, from sources.

I am not sure it makes difference with 3.0.2.

I fixed the display freeze by slightly modify the EDA_3D_CANVAS::OnPaint( wxPaintEvent &event ) method:

I removed:
event.Skip( false ); (not useful)
and
wxPaintDC( this );
This is when deleting this line i do not have any freeze.

In OpenGL samples, you can see wxPaintDC pdc( this ) in paint events, but now I am thinking it is
not needed and can (and perhaps must) be removed (I am thinking the associated comments are very
old) at least in wxWdgets 3.0

Moreover, in wxWidgets compiled with GTK3, in the EDA_3D_CANVAS::OnPaint(), I have an assert error
for wxPaintDC pdc( this )
(wxPaintDC not allowed in non native Paint events).

Therefore I think now wxGLCanvas::OnPaint() in a special case, and does not need a wxPaintDC
declaration.


Here is my change:
