crash when measuring using internal generator

[24fpsDaVinci]

i'm testing the 22pt greyscale patch list using the internal generator like in the example photo. It either hangs or crashes immediately when I press measure patches. I'm on argyll 3.2.0 and spotread is in path. Running Fedora wayland.

You're supposed to build in release mode, this should only happen in debug mode.

I switched to building release it still hangs when I press measure patches or measure selected patches, I can see the i1d3 flash once to indicated its connected when i press start spotread..

here it hangs when i'm measuring "selected patch" 1024,1024,1024 should be pretty fast normally with spotread. I'm running the binary from target/release directory.

and running spotread manually

a@fedora:~/pgen_client-1.0.2/target/release$ spotread

Place instrument on spot to be measured,
and hit [A-Z] to read white and setup FWA compensation (keyed to letter)
[a-z] to read and make FWA compensated reading from keyed reference
'r' to set reference, 's' to save spectrum,
'f' to report cal. refresh rate, 'F' to measure refresh rate
'h' to toggle high res., 'k' to do a calibration
Hit ESC or Q to exit, any other key to take a reading:  

 Result is XYZ: 139.091458 143.734469 167.829302, D50 Lab: 114.911651 0.680851 -27.716282

Can you run it with more verbosity, using -vvv.

pgen_client -vvv

ok i attached the log instead, the formatting on github causes a really long line if I pasted it here.

log.txt

I guess there's not enough logs. I'm not sure what's happening.

[24fpsDaVinci]

hmmm, are you also using argyll 3.2.0?

[quietvoid]

Last time I've used it was probably still 3.1.0. Would need to try it.
