Emulator

There seems to be a problem with the Auto aspect ratio setting. Probable regression related to the hybrid XFB feature? Using builds downloadable from dolphin-emu.org, it happens with 5.0-5874 (latest commit "Hybrid xfb"). Doesn't seem to happen with 5.0-5833. Still happens with 5.0-6184.

I'm using the Direct3D 11 backend on an AMD FirePro W5100 graphics card.

There are occasional display glitches when aspect ratio is set to Auto. It seems Dolphin mis-detects a frame as being of a different aspect ratio. Thus for that frame, the image is squashed horizontally (vs 16:9 for all other frames). If I set aspect ratio to 16:9 there is no glitching. When not in full-screen mode, the window size may spontaneously increase when a glitch happens.

I tested GXPE78 "Sphinx and the Cursed Mummy", image MD5 4e635d238507f1898b40bd7ab0491155. Save state created with 5.0-5874 (~12.3MB): http://www.mediafire.com/file/5t5qk2qdzm852hh/GXPE78.7z
