Bug #1: VF Curve loads with changes after system reboot.
 
How to reproduce:
1- Set up a custom VF curve manually on PX1 (for example, I have an undervolt curve for my RTX 3090 FTW3 Ultra that stops at 875mV @1905MHz).
(Note: Make sure you note the values for the custom curve, to compare at step 4)
2- Save to a profile.
3- Shut down the system, and then power it back on.
4- Take a look at the custom VF curve in PX1 after the system reboot, and notice that some of the points on the curve have been moved up or down.

Curve after reboot:

 
Bug #2: Changing custom fan curve and clicking Apply resets custom VF curve to the default VF curve.

 
How to reproduce:
1- Set up a custom fan curve (for instance, 30% under 50C, up to 50% at 70C, then up to 100% at 90C).
2- Enable fan curve control.
3- Make a custom VF curve by dragging the points on the VF graph, for example to set up an undervolt.
4- Apply.
5- Go back to the custom fan curve control menu, make a change to the fan curve (for instance changing the fan curve graph, or setting up a temperature hysteresis).
6- Apply.
7- Go back to the VF curve menu, notice your custom VF curve set at step 3 has been overridden with the default curve.
 
Cards Tested: RTX 3090 FTW3 ULTRA (24G-P5-3987-KR) and RTX 3060 XC (12G-P5-3657-KR)
PX1 Version: 1.1.7.0
 

Hello Peter.
 
I do have the settings 'Start With OS', 'Start Minimized' and 'Apply previous settings on load' enabled.
 
I've just reproduced both bugs on a fresh install of PX1 1.1.7.0 (ran steps 1, 2 and 5) with my RTX 3090 system.

Here you go:

Latest Nvidia drivers (non-beta) and latest version of PX1 used.
