In incus, I had the same setup of an LCX container with a Docker container inside of it. I passed 1000/1000 to the LXC container but the LXC container’s default root user has a an ID set of 0/0. So I had to pass 0/0 to the Docker container, not 1000/1000 to get the read/write permissions working.
That may fix your issue as it’s basically the same tech, just different automated things implementing the LXC container!
One drive does suck nards, but for your double clicking; logitech has been using shitass switches to detect clicks for a while now. They sooner rather than later fail to click once. Only solution I’ve found is to replace the switches (hard mode), or keep using the logitech mouse I have from 2009.
It’s sucks, but you just gotta go for another brand. Even razer doesn’t have such a rampant double click problem.
Logitech enshitified their dominant market position by cheaping on switches - works for them, they sell more mice (if you don’t put together they’re the source of the problem and it’s not a one-off issue).
