Comment 1 David Redondo 2019-10-23 12:32:18 UTC

Does it happen on X or on Wayland? Do I understand it correctly that the crash happens during the selection of the region and not for example upon start of the selection overlay?

Comment 2 Nate Graham 2021-12-13 21:16:02 UTC

Ping. In addition Spectacle's code has changed a lot since this crash was reported, and there haven't been any more reports in over two years. Are you still experiencing this issue in Spectacle 21.12?
