Score becomes invisible and other artefacts
2.0.3 on Win 7/10
Bug confirmed in both Win 7 and Win 10.
1. Open the attached Music XML file. Make sure you are in horizontal scrolling view. The score is 24 bars long over 3 pages.
2. Now inspect Layout > Page settings. The third page is missing in the preview. You will see a similar bug in the Navigator.
3. Now change to vertical scrolling view. The third page of the score becomes invisible. However, you can play it back and the notes will show up locally as the cursor moves.
Edit: See the attached MuseScore file. This is the same as the above but after a bit of clean up-work.
4. Click on any element in the fourth system. The system brackets disappear. Click on the page-break and the page break disappears.
