As suggested in message https://lists.freedesktop.org/archives/mesa-dev/2018-March/187773.html I tested various Mesa versions with command $ LD_LIBRARY_PATH='foo/mesa_n_version/usr/$LIB/' LIBGL_DRIVERS_PATH='foo/mesa_n_version/usr/$LIB/dri' firefox 17.0.5 which packages have been made in build https://copr.fedorainfracloud.org/coprs/germano/mesa_test_regression/build/720909/ 18.0.0 which packages have been made in builds https://copr.fedorainfracloud.org/coprs/germano/mesa_18/build/720272/ https://copr.fedorainfracloud.org/coprs/germano/mesa_18/build/720216/ I experienced the problem with both of them. Now I will proceed in testing Mesa 16.x
