Did you perform a full shutdown of Windows (Windows doesn't fully release the partition on a normal shutdown)?

I'm pretty sure that my desktop is drawn at 144 Hz (on the primary display) and xrandr also tells me that that's the active mode. 🤷‍♂️

Edit: This is with Nvidia (proprietary drivers) and VRR monitors.

Is that generally an issue on Linux Mint / Cinnamon X11? I have a 144 Hz and a 70 Hz monitor and they seem to work fine....

I'm not sure I follow... Did the Fedora Council actually take a decision?

That looks like a software issue... I would try a different distro or a different version of Ubuntu (e.g. 22.04).

You could also try to switch the kernel version. Ubuntu 22.04 currently supports two different versions: 5.15 and 6.5, you could switch to the other one and see if the problem also occurs there.

That looks quite weird... RHEL 9.2 was patched in February. RHEL 7 and RHEL 8 have now been patched too, but RHEL 9 (9.3) is still vulnerable?

AlmaLinux is effectively a downstream of RHEL, so it inherits a lot of RHEL's pros and cons. I think, from a technical perspective, it makes a lot of sense for professional applications. It has a rock solid base OS that only changes rarely, which has lead to widespread support among professional (commercial) software. On top of that you get more regular updates to hardware support and (some) applications. You also get very long support times, which can make sense for some use cases.

On the hand, this model certainly also has its downsides. Towards the end of the life cycle, the packages get very old, especially the base OS (e.g. RHEL 7, which goes EOL this year, ships with gcc version 4.8). If you care about having the latest and greatest packages, this is not a distro for you. It's also not clear if Red Hat will try to further crack down on their downstream distros...

Overall, I think it's a good choice for a professional environment, where you don't need bleeding edge packages. Some commercial software also doesn't give you a lot of other options. For personal use, I'd probably look for another distro, unless you're looking for a very slow update cycle.

If you exceed the capacity of the PSU and trip one of the protection circuits, it should completely cut power. When that happened to me, it needed a power cycle before it would boot again. So I'd say that something goes wrong after the PSU. It could still be a voltage drop at the GPU (see other comment regarding cables). Maybe even just a driver/software issue.

You could try to downgrade simple64 to an older version: https://docs.flatpak.org/en/latest/tips-and-tricks.html

The article says they are aiming for 1W in the next couple of years, which can probably do it.

They won't magically improve the power density by three orders of magnitude. They're just trying to defraud their investors.

I expected to see Technivorm but this is specifically espresso machines.

Here's the Warranty Data for Filter Coffe Makers if you're interested. Not enough data for Moccamaster though.
