Meh. I've done low-level embedded/mobile for a long time now. This actually sounds like a totally reasonable RF interference issue. 2.4Ghz is funky & has desense issues with lots of internal busses (not a HW engineer so not sure why that band specifically). Also radios typically have to accept interference which means the radio would "stop working" rather than causing the display to work weirdly (ironically a much easier failure mode to display/diagnose/notice).

when the late 2016 macbook pro came out with only usb-c i had to buy a usb dongle from amazon (the one included had not enough ports). if i booted the macbook in windows, with the dongle connected the wifi would stop working (the 2.4ghz one) and the 5ghz would work.

Duly noted! I've been out of the embedded space for a long time (I think the last board I worked with was i386EX based) but I'm getting back into it now with an ESP32 so this might actually come in handy. Thanks! :)
