Puzzling. The call to GammaSetSize() looks to be the right fix. :|

Could you add this bit of debugging to confirm that the GammaSetSize() is
taking effect:


diff --git a/src/sna/sna_display_fake.c b/src/sna/sna_display_fake.c
index fa26bda..b504f3f 100644

                if (!RRCrtcGammaSetSize(crtc->randr_crtc, 256))
                        goto err;

+                      crtc->gamma_size, crtc->randr_crtc->gammaSize);
        }

        sna->mode.num_fake++;
