+Subject: [PATCH 17/50] egl/dri3: fix segfault in eglCopyBuffers
+
+The loader_dri3_copy_drawable function expected the drawable to have
+a fake front buffer, resulting in a segfault if there wasn't one,
+when dri3_fence_reset was called.
+If there is no fake front buffer, but there are back buffers, use the
+current back buffer.
