Can you test again to confirm if the issue is resolved???
I test again with Stellarium revision 6546 with replaced StelMainView.cpp from revision 6577
This issue occur in revision 6546....
But after the replacement of StelMainView.cpp, I cannot reproduced the issue with this revision....
Maybe change in revision 6577 resolved this issue.....
