Package: mpv

Dear Maintainer,

mpv --vo=opengl-old fails to render OSD (draws empty rectangles instead)
when sub-option rectangle is 1 (it is set to 1 by default on some
video-cards [with mesa ATI r200 driver], otherwise can be enabled by
--vo=opengl-old:rectangle=1).

Notes:
1) This bug does not affect testing and upstream (--vo=opengl-old was
completely removed since mpv-0.8), only jessie is affected;
2) --vo=opengl-old is not used by default, however, it was suggested by mpv
for very old videocards that lacks OpenGL-2.0, and on some of such cards
rectangle suboption is enabled by default.
Same as the other one, I don't think this issue is serious enough to warrant
a stable update, sorry.
  Can you use a different vo? (e.g. xv, x11 or sdl).
Sure, on this system mpv by default uses xv (it tries opengl [non-old] first, fails [as opengl version less than 2.0], and fallbacks to xv). There can be some performance advantages in using opengl-old (as it blits OSD/ass on GPU, while xv renders them on CPU) in some use cases [or not, I have not benchmarked/profiled it yet; there can be some theoretical reasoning for opposite too].
