Track selection change can crash reaper [Linux]

FeedTheCat · 07-09-2019, 07:30 AM

Tested on Windows and Linux. Only affects Linux.

Prerequisites:

Settings: Open Track FX window on track selection change is enabled

How to reproduce:

1. Create 2 tracks
2. Add Megababy JSFX to one track
3. Open FX chain
4. Bind actions 40418, 40419 to hotkeys (Item navigation: Select and move to item in previous/next track)
5. Use consecutively until reaper crashes

Workaround:

The crash seems to be caused by the FX chain getting focus when changing track. Setting focus back on the
arrange window after changing track selection, e.g. with reaper.SetCursorContext(0) fixes the issue for me.

In case the coredump helps:
Message: Process 5404 (reaper) of user 1000 dumped core.

Thanks, fixing! (This can also affect macOS!).

Side note: you need the options enabled to only have one FX chain visible at a time, and have it follow selection.
