Really not good enough from AMD. I wonder if Intel wasn't a complete dumpster fire right now if they would still cut off the fix at Zen 3 (I doubt it). There's really no reason not to issue a fix for these other than they don't want to pay the engineers for the time to do it, and they think it won't cost them any reputational damage.
I hate that every product and company sucks so hard these days.
Fun fact about mushroom toxicity by contrast. Because the mushroom is only the reproductive organ of the organism, and you're basically doing it a favour by picking it and spreading its spores everywhere, theres no evolutionary pressure for it to evolve toxicity to humans. So the compounds in mushrooms that are toxic to us likely exist for other purposes, and are only toxic to us by coincidence.
For this reason the proportion of species of mushrooms that are safe vs. the number that are toxic is greater than with plants. Because plants have had selective pressure to evolve poisons that discourage or prevent herbivory. So if you walk into an unfamiliar forest and pick one plant and one mushroom to eat at random, it's more likely the plant is the bigger danger.
Of course I absolutely do not condone eating plants or fungi at random unless you intend to have a painful death.
I've only been fully on Linux for about 4-5 months, but am yet to experience any issues on Fedora KDE with Wayland. Previously while I was distrohopping I was having a bit of a rough time but since settling on Fedora and with Plasma 6 it has been smooth sailing.
I'm using an AMD 5700X/B550m and RX 6700 XT. Also with two mismatched 1440p displays (different refresh rates).
