Fetched RetroArch and compiled it using the libretro-super git repository scripts, and I used sudo make install to install as normal. After that, I copied over the configuration file and made a few changes to my paths and tried all of the available video backends, but I received this error with the gl and xvideo backends.
RetroArch [ERROR] :: Cannot open video driver ... Exiting ...
RetroArch [ERROR] :: Fatal error received in: "init_video_input()"
Upon trying sdl, RetroArch immediately caused a segfault and exited. A git bisect and a lot of testing revealed that the regression appears in this commit: [c54af1907643c3e9438bf879943e0b87e281acab] Purge SDL/GL context.
I hope this helps, let me know if you need more information
