Hey! So I was wrong (again), this is not glamor_composite_choose_shader() failed which is the problem, the rendering issue comes from glamor_poly_fill_rect_gl() (the plain ackground is garbled, not the actual content, if that makes any sense).
If I force glamor_poly_fill_rect_bail() from glamor_poly_fill_rect() rendering is fine. It is also worth noting that the glsl version on this particular hardware is 120, so we are using glamor_facet_polyfillrect_120... I also noticed that not showing the GtkEntry box avoids the issue, but I can't make sense of that. Still digging, meanwhile if someone else has an idea :) Cheers, Olivier _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel
