This is all totally fine for me (upscale, downscale, fullscreen with 
upscale, fullscreen with downscale, OSD on top of all of those things).

Can you describe precisely how you got that crash, and ideally a 
backtrace to go with it?

I also tried anamorphic video.  There is something a bit strange going 
on because I got the behaviour you described with extra black bars when 
playing in a window, but it did the right thing once it went fullscreen. 
  Maybe it's just that the window is made initially with the wrong 
aspect ratio?
