Sublime text 3 using 100% CPU on idle and with index set to false

Question

This is not a duplicate of Sublime text 3 using massive amount of CPU on idle

Here is why

OS: Ubuntu 20.04.6 LTS

I only use Sublime as a file editor and not a code IDE, meaning I mostly have unsaved tabs open with plain english test. But Yes, I have folders open on the side, all folders contain different language code and xml files. none are 'compilable' projects though, just standalone python, php or shell scripts.

Index is false and package control has only 2 packages

{
"bootstrapped": true,
"in_process_packages":
[
],
"installed_packages":
[
    "Material Theme",
    "Package Control",
],
}

No idexing is running

BUT still the CPU is at 100% most of the time. any more info I can check as to why is it so, please let me know
