Ok it isn't working anymore. Please mark this bug as invalid.
When I have the time, I will rescreenshot.
Oh I forgot to mention, in survival when I try this, it stops me from applying Soul Speed 1 to the pickaxe, but allows Soul Speed 2 and 3.
I was in survival mode. I changed my game mode after I saved the screenshot of the F3 menu.
This is on singleplayer and still happens.
I'll try on Vanilla (The mods are just for performance improvements).
No I am in survival mode.
Have you tried using your own JDK? (https://jdk.java.net/17)
Turns out 1 of my fans were spinning at 80RPM and the other one was spinning at 5200RPM. Had to modify the 2nd fan's thermal multiplier up to the max (which was 20x) and it started spinning at 1700RPM. I no longer have these thermal shutdown issues. So it had nothing to do with Minecraft, HP just did an awful job at their BIOS updates.
I now request this "bug" report to be closed.
If it was, it wouldn't be doing a good job if it was melting my laptop (373K = 100*C)
Minecraft is cycling the RAM that is given each second, which causes more power to be used, and increase thermals.
"RAM Cycling" is dangerous when it comes to the longevity of your computer. In most cases, a trojan would use RAM cycling to make enough space to execute a malicious piece of code.
What you see in that gif is what happens every couple seconds. Sure it is a gif, of course it would be looped, but my point still stands: what you see in the gif is what actually happens in real-time.
For me, after turning my computer back on, it would still be running.
Talk to the developer of the Flans Mod about this bug, or if there is a GitHub page, open an issue.
