Tie position incorect over line break without clef
On the last note of the last bar of a line, create a tie to the next note (next bar on next line). In Format>Style>Page deactivate option "Create clef for all systems". In this case, the tie seems to connect the first and second notes of the second line.
Workaround; closing the file and reopening it seems to fix the tie position.
Attached : simple mscz file showing the issue + screenshot
Note: upon file opening, the tie will be OK, activate the "clef for all systems" option and then deactivate it to see the bug.
