it seems the #1 time it does anything, it's deciding that your second input device isn't transmitting for 0.1 microseconds so now it's switching back to input device 1 instead. because fuck you
hmm. if I switch inputs immediately after booting this raspi, I see it start up, and start to boot, then it goes out of signal and then WHOOPS HDMI SWITCH
either my raspi is powering itself off as it boots (weird, but possible I guess) or when it switches from the text-mode boot screen to the... graphical text mode screen? it's going out of range and this monitor is deciding it doesn't like it anymore
