PPK2 and Power Profiler desktop: time scale way off

Did a quick search and it seems I am not the only one experiencing this issue Disappointed But can't find a solution.

I just got a PPK2 and started testing some devices (ESP8266). I quickly noticed that the time in the graphs was completely off.
Have a look at this screenshot:

Without even activating the power supply, just starting measuring and stopping 5 seconds later. You can see down in the log:

19:17:20.698	Sampling started
19:17:25.735	Sampling stopped

But if I click on SELECT ALL it says 1.606 seconds
So basically it reports around 1 second for every 3 actual seconds.

It doesn't matter how many samples per second I take, it does it all the time.
Zooming doesn't change anything, it is still wrong.
Tried with 3 different USB ports already both USB2 and USB3, different cables too.
And the DUT I don't think it matters, tried a few already but same problem regardless.

Should I return the unit? Or is it a software error? Any workaround?

System:
Manjaro/KDE
Linux Kernel 6.0.15
AMD Ryzen 5 5600X
16GB RAM
MSI B450 Tomahawk Max II on latest BIOS: 7C02vH9 2022-08-15 (it was happening with a previous BIOS too)

Power Profiler v3.5.3

Edit: tried on windows, same problem.

Edit2: tried on an ancient Intel laptop, with windows, and it works fine. So it is not the hardware, it is the software that is broken. And has been broken for 2 years according to the reports: github.com/.../141

  • I just bought a new computer and now have exactly the same problems. I hope the problem is solved quickly.

    Previously with Intel CPU no problems at all. Perhaps there is a correlation.

  • Hi , I have also the timing issue. When i click on 10sec for a screen , the capture full windows is like more than  two times the selected value. The selection window is also not giving the good duration too:

    My advertising period is 10sec, i can also count it. But selected time said 3.566sec , that's not correct.
