Okay, y'all, REALLY proud of this one!
Current @npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl dev builds are looking great, EXCEPT the frame rate in the live preview got worse in the new custom linux OS. Like "unacceptably bad" worse.
I haven't really looked at the live preview code since like July 2021. But I did find some areas to optimize! Squeezing every bit out of it that I could think of yielded enough to make a substantial improvement to usability. Just enough to nudge it over the "okay, it's not terrible" threshold.
