Failure to show courtesy key signature for change to C major / A minor
This fault has been reported on the forum "Support and bug reports":
Possible cause or contributing factor: when measures are so long that there is only one measure per system, I have seen two separate scores where MuseScore fails to show any courtesy naturals prior to a change to C major /A minor on the next system.
The attached empty score demonstrates the problem in measure 3: the double barline inserted by MuseScore indicates that there is a change of key signature, but the courtesy naturals are missing. Measures 4-7 are in C major (or A minor).
