I opened these as separate bugs. One for the settings page and one for the sluggishness and checkbox issues on the banks page. I hope that's okay. If there's not enough detail (e.g. about my platform), let me know. https://chirp.danplanet.com/issues/10171 https://chirp.danplanet.com/issues/10172
There was one other UI issue I didn't mention in the last message. The vendor and model dropdowns in the radio download/upload dialogs are cut off for me. I think that's probably due to my high DPI display. I opened a bug for that too. https://chirp.danplanet.com/issues/10173
Yep, perfect, thanks. I poked around last night on windows and mac and couldn't get anything resembling sluggishness on those machines with oodles of memories and banks, so it might be a GTK thing. I don't have a hidpi linux machine to test with, but I can run it over remote X which usually highlights pathological UI behavior.
Thanks!
