Femto - setIntProperty() not working and wrong frame rate

Hi,

I run 2 Femto sensors in sync mode. I set the exposure, then I get the desired profile and finally start the profile. Most of the time, everything works as intented. However, sometimes, the second sensor remains in auto-exposure mode. This happens 10-15% of the time.
Some other times, I get the wrong frame rate (ask for 30fps, get 20/25fps). This occurs less often than the first issue and can happen for either first, second or both sensors.
I don’t think there is a link between these two issues (at least I haven’t seen any correlation).

I tried waiting a bit between the moment the exposure is set and the moment the stream starts.
Any idea of what the problem might be?

Thanks!
