No, that's a different protocol, the tearing patches, already merged, but i believe we're still waiting on some patches to the kernel to get them fully working(i think it was kernel 6.8 that had them), Nvidia's drivers also need to add support for it, they've given no timeline for that so far however

You can, infact there's outright a mesa git runtime one can add, i don't imagine too many systems roll so fast as to outpace it https://docs.flatpak.org/en/latest/available-runtimes.html

Your best bet is to find a car where its easiest to disable the antenna/cellular modem for, so look for a car that has a fuse for the DCM(digital communications module) you can pull, as having it be a fuse means you can readily reconnect it should you need to, try to find its schematic online, or find the repair manual for the car or use a car maintenance program,

Apparently its also possible to call the car company and ask for an opt out when serviced,

I vaguely remember some people experimenting with replacing the head unit with aftermarket ones, but no idea how well that would actually go in practice

mokutil --disable-validation

Though this sounds more like a case of needing to disable secure boot in your bios ? As far as i know Mint has no secure boot support, and the mokutil keys of a previous installation wouldn't affect a fresh one

Two utilities that may be handy for you here:

Pakrat: Automates and simplifies the process of creating alliases for flatpaks, good if you just need to make a few programs be simplified

Fuzzpak: Lets you do fuzzy searches for flatpaks(as in you just write fuzzpak inkscape and it auto looks for something with inkscape in the flatpak folder and launches it), good for when you want to simplify launching flatpaks in general without doing the process of configuring stuff manually

Are you using Firefox within a flatpak perchance ?

There seems to be a bug to it relating to use of bitmap fonts, you can fix the issue by disabling them via a config file in firefox's fonts: https://bugzilla.mozilla.org/show_bug.cgi?id=1621915

PDF4QT, bit of a newcomer, but its a free and foss pdf editor with the capabilities of propriatery equivalents: https://jakubmelka.github.io/

There's a few options

Newpipe, uses it's own extractor, also can act as a player for SoundCloud and Peertube, there's also a fork with SponsorBlock: https://newpipe.net/

Libretube, uses the Piped api, generally seen as the one with the best UI: https://github.com/libre-tube/LibreTube

Clipious, uses the Invidious api: https://github.com/lamarios/clipious

Could also watch videos in a browser from an Invidious or Piped instance I guess

And while I'm at it I'll also mention there's a client option on desktop too, Freetube: https://freetubeapp.io/

Fennec enables access to about:config, so making all of arkenfox's changes manually(by viewing its user.js and toggling it in about:config accordingly) would also be an option, none of arken's toggles are desktop only as far as I know

You can take a crack at using Geddit I suppose, doesn't use the reddit api so should keep working, but is in turn kinda janky as a result: https://github.com/kaangiray26/geddit-app
