Color LCD v3 shows always random characters w/ OpenEVSE v6.5

I replaced most of the electronics in my OpenEVSE, including a new OpenEVSE v6.5 and Color LCD v3 + Temperature. (Still using my earlier WiFi board, no longer using separate temperature.) I also replaced my Struthers-Dunn relay with a new Packard relay.
The charger works fine and WiFi controls also work fine (changing the current limit, LED brightness, viewing status / temperature / time). However, the LCD display always shows gibberish characters. They seem to change at roughly the times I'd expect based on charger state changes, but they always are nonsense.
From other threads it sounds like some LCDs have different resistor values that make them more susceptible to noise, but my understanding is that's old versions. It also sounds like it's more likely the cause if the LCD shows correct info initially and then gets garbled. Might resistor values be a problem with this one?
Are the LCD v3 and OpenEVSE v6.5 compatible? Support said they were before I ordered but I'd like to double check.
Thanks for any advice! Not critical but it'd be nice to have info on the LCD as well as the web portal.
