Beam placed in middle between high and low notes causes part of beam to be incorrectly positioned

The score contains two 16th notes surrounded by two 8th notes. The 16th notes are high on the staff and the 8th notes are low on the staff. If the beam is above (see Figure 1) or below (see Figure 2) all notes, it appears correctly. If it is above low notes and below high notes, in the middle (see Figure 3), the 16th-note beam portion is positioned quite poorly.

Hi, and thanks.

I just tried version 2.0.0 (rev. e146aba), and in Continuous View, the beam works properly. However, in Page View, it's worse--rather bizarre, actually. :-)

In Page View, as I drag the beam up into position, the 16th notes move increasingly to the right, over into another measure! When I exit edit mode, stems on the 16th notes are then drawn all the way down to the bottom of the page. Interestingly, if I switch to Continuous View, everything looks good--and if I then switch back to Page View, it still looks good.

Here's an export showing the 16th notes after they've moved to the right:

I can definitely reproduce this as well, using a build I just did yesterday. Here's a screenr video:

The way I created the sample was to enter the notes then set the beam on the last note to "middle of the beam".

EDIT: after using the same file to test something else, I can no longer reproduce the bug, either. So it seems dependent on something. But I can't figure out what. In trying to reproduce the bug again, I tried to remember *exactly* what I did the first time. One of the steps was double clicking the "middle of beam" icon after the cursor had already moved on to the rest after the note. I now see that this triggers another bug (or different manifestation of the same one), where the stem on the last D extends upward to infinity. To see this, click the eighth rest in the attached file, then double click the "middle of beam" icon.

I am able to reproduce this as follows)

1) note entry node, enter 4 D (change octave as necessary to make this just below treble staff)
2) keep entering:3 G Ctrl+Up G 4 D Ctrl+Down
3) double click beam
4) drag left handle upwards

Beam appears correct as you drag it between the notes. Keep dragging up past the top notes and flips, which is correct. Now start dragging back down. Beam fails to flip back.

FWIW, while I can still reproduce the bug following the steps in #6, the beam corrects itself if you, for instance, double click one of the notes then press Esc.

Status (old) active fixed

This all appears fixed now - the steps in #6 now correct the layout immediately upon leaving edit mode (as of a fix I made the other day).
