Raspberry Pi 3 No Automatic Refresh Rate switching (LE 9.2.6)

  • How do I get the RPi3 to automatically switch refresh rates with a clean install of LE 9.2.6?

    The connected display supports:

    at the gui:

    Code
    tvservice -s
    state 0xa [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 59.94Hz, progressive

    For example enable Full HD HDMI modes for Stereoscopic 3D is set. But when I play 3D MVC content this is the mode I get:

    Code
    tvservice -s
    state 0xa [HDMI CEA (16) 3D T&B RGB lim 16:9], 1920x1080 @ 59.94Hz, progressive

    If I manually change the refresh rate to 23.98 in the GUI before starting playback I will get:

    Code
    tvservice -s
    state 0xa [HDMI CEA (32) 3D FP RGB lim 16:9], 1920x1080 @ 23.98Hz, progressive

    I've whitelisted all the 1080p resolutions my display supports (like 1080p24, 1080p23.98, etc.), but it won't switch into any of them automatically for 2D or 3D content. It just always stays at what the GUI is set to. There is no option to enable automatic refresh rate switching in the GUI like I've seen in older versions on other HW, I checked both Advanced and Expert modes.
