All Cores Show Maximum in Monitor Mode

### Step 1: Describe your environment

* System (Intel/AMD/Raspberry Pi etc): Intel
* OS version: Mint 21.3
* s-tui version: 1.1.5
* Installation method(pip/PPA/source code): DEB from Github

### Step 2: Describe the problem: When I run S-TUI, all cores show at maximum (almost maximum) MHz.
#### Observed Results: Using other CPU monitoring programs such as htop, i7z, turbostat, the cpus and threads show at idle or very small amount of load. Only S-TUI shows cpus at maximum/almost maximum.

* What happened? (Traceback of a crash/Image/description):

#### Debug Results, output of `s-tui -d` created in a file `_s-tui.log`:
[_s-tui.log](https://github.com/amanusk/s-tui/files/14103712/_s-tui.log)

* Replace this with debug output *
```
