sdl2: redraw correctly when scanout_mode enabled.
When scanout_mode enabled, surface is out of sync with actual screen. In such case, we just call sdl2_gl_scanout_flush to do redraw. This fixes bug reported in https://lists.freedesktop.org/archives/virglrenderer-devel/2018-July/001330.html Signed-off-by: Tao Wu <lepton@google.com> Message-id: 20180726225900.180698-1-lepton@google.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
