Incorrect key signature after toggling concert pitch on staff with instrument and transposition change at start
When I open the attached file: everything is fine (see screenshot_01_...).
Then I press the button "transposed score" and everything is still fine (see screenshot_02_...)
Now when I switch back to concert score a new and incorrect key signature appears in the 2nd alto. (see screenshot_03)
From now on I can switch between both concert and transposed views as much as I want - this incorrect keysignature remains the same and is consistnt in both views (see screenshot_04_...)
A suggested work around of re-stating the key signature does work but has 2 disadvantages:
- I have to do it everytime a player changes the instrument mid-song
- the "new" key signature (that is the same as the old one) appears in all parts mid-song, thus creating unease and shakiness with the performers ("What is happening???" where there is nothing happening..)
I have not checked if this behavior exists only on parts with a change of instruments mid-song or if you get this misbehavior only with certain instruments, but it did occur a few times in my past scores.
Since I found a few similar issues in the issue tracker (but just not quite the same or with the same version of musescore), it looks like a fix of code would much be apprecheated by the community.
