I’m not a fan of the xfce UX at all, and multi-monitor support still has a lot of issues (under Debian 12), but I am pretty sure having different refresh rates is possible

It’s most likely watching Youtube with your VPN that’s broken then, not NewPipe. Youtube implemented Captchas for IPs that generate a lot of traffic/a lot of people are using. That’s how they are trying to kill frontends like invidious that proxy the requests. NewPipe by default uses your own IP so it doesn’t have that problem. If you use a VPN IP that a lot of others are using too, you’ll get that same problem though.

The version now called “Lawnchair Legacy” was very old and unmaintained. They’ve been working on this new version in the meantime.

If they are public, no it is not illegal. If they are not public, but I have them because I provide a service to you, then yes it is illegal (most likely). In this case it is public information, and not even personal information. It is a plane identifier and that plane’s location. The only reason that tells you anything about it’s passenger is because said passenger is rich and entitled enough to own their own plane and use it for themself. It’s like buying the Empire State Building to live there by yourself and then complaining about someone tweeting out your address.

As long as your apt sources (/etc/apt/sources.list) are set to bullseye (and not eg. stable) you won’t “accidentally” upgrade to bookworm. At least that’s how it works in Debian, I assume raspbian is the same.
