Fucking called it
Only some Pixel 4a phones are affected, apparently.
You know… the stuff they’re doing to some Pixel 4as - reducing charging speed, limiting charge level, etc - those are the same things EV manufacturers do when they’ve got known faulty batteries catching fire and are trying to work around the issue with software.
Doing it to certain devices which you can look up by IMEI, that sounds a lot like something you’d do if you had a certain batch of batteries catching fire and knew which devices had those batteries.
More than a year after end of life, Google suddenly decides “stability of battery performance” is such a big issue that they’re going to pay compensation to people? That isn’t suspicious at all.
You don’t seem to have an Nvidia Vulkan driver installed.
Your system can see the Intel and Nvidia GPUs, but it only sees an Intel Vulkan device and a software emulation device (llvmpipe).
Proton needs Vulkan for graphics to work.
