| Summary | 0006556: Dragging an item "far right" results in ardour hanging | ||||
| Description | Using Ardour 4.2 on Archlinux x64 Steps to reproduce: - Create a session with a MIDI track - Zoom out as far as possible - Draw a MIDI item - Drag the midi item to the right screen border -> Ardours GUI locks up and hangs for a long time (~30s) Attaching GDB yields the info that most of the time seems to be spent around Timecode::timecode_to_frames_per_second(Timecode::TimecodeFormat) | ||||

Forgot to add: GUI will become responsive again eventually. After the lockup period the item will not end up where it has been dragged to. |

The current Mixbus 3.0-1268-g065d938 crashes or shows the same behaviour on Windows. Zooming out as far as possible seems to be enough to trigger this behaviour. |
