found this one already a while back, I think since the implementation of background processing. Changes in the "Resolution" feature (Print Settings > Advanced > Other > Resolution) seems not to be watched to trigger re-slicing when background processing is enabled.
Minor bug with low priority I guess, will just show when one tries to actually change the resolution values and observe the effects to the printing paths... But anyway, just for the records, it's there, this bug ;)
Bugfix: changes to the resolution config option didn't trigger reslic…
Good catch! Fixed.
