| Summary | 0010136: Pianoroll editing stops working after certain region manipulations | ||||
| Description | After splitting and moving a longer MIDI region, the pianoroll shows glitches when zooming with the mouse wheel. Notes then start to disappear, making it impossible to edit the region in the separate window or in the properties box. | ||||
| Steps To Reproduce | 1. Create a new session. 2. Create a fairly long MIDI region (about 1 minute or so). 3. Draw some notes in the last few bars (as shown in ar-screenshot01.png). 4. Note that at this point, zooming with the mouse wheel in the properties box becomes problematic due to unpredictable horizontal scrolling. 5. Split the region just before the first notes, delete the empty region, and move the region with notes to the beginning of the session (as shown in ar-screenshot02.png). 6. After some zooming with the mouse wheel – both in the separate pianoroll and in the pianoroll within the properties box – glitches start to appear: the grid and notes disappear, making editing in the pianoroll impossible (the attached animation shows the problem). | ||||

Couldn't upload the animation. See it here: https://oc.lh2.pl/s/yFXTB9S9c2F3H53 |

I could not reproduce the initial parts of the report, but could easily reproduce the "split region; delete; move" part. This is now either fixed or at least much better as of commit c2c6581ddb |

I couldn't find such commit (at least in Github repository). Anyway, I can confirm it’s much better in rc5. I was still occasionally able to hang editing in the bottom panel, but it’s now much harder to trigger and far less deterministic. Regarding the first part, I can still reliably reproduce the minor glitches mentioned above in rc5: 1. Remove the Ardour config (to start with a clean state). 2. Start a new session, create a MIDI track, and draw a region about three minutes long. 3. Draw just a few notes at the end of the region. 4. Now try zooming in and out on the notes in the "properties window panel" using Ctrl + mouse wheel. It's hard to zoom in on the notes, as the pianoroll scrolls back to the beginning of the timeline and the grid randomly disappears. Overall, this makes editing difficult. Zooming with the +/- buttons works (mostly) fine. This capture shows the behavior: https://oc.lh2.pl/s/TFSSNNPYgSPq4NS |
