Comment 1 Nate Graham 2023-09-15 16:08:55 UTC

A fascinatingly detailed set of steps to reproduce; I appreciate that. Unfortunately when I apply them as faithfully as I can on Plasma 6 Wayland, I can't make Spectacle crash.

Any chance you could try again with the recently released 23.08 version? Thanks a lot!

Comment 2 BPMb 2023-09-19 13:56:17 UTC

I run KDE Neon, I guess that would involve me to upgrade to the Developer Edition Stable Branch of KDE Neon?

Comment 3 Nate Graham 2023-09-19 15:44:32 UTC

Neon User Edition should be shipping that version fairly soon, if it hasn't already.

Comment 4 BPMb 2023-09-19 19:40:57 UTC

I have spectacle version 23.08.1:

spectacle -v
QSocketNotifier: Can only be used with threads started with QThread
spectacle 23.08.1

Comment 5 BPMb 2023-09-19 19:42:03 UTC

Forgot to add, the issue is still there. I'm not using Plasma 6 yet by the way, do you think that might be the cause?

Comment 6 Nate Graham 2023-09-20 17:25:21 UTC

Thanks.

Comment 7 Noah Davis 2023-09-25 05:37:37 UTC

I am able to reproduce this with git master spectacle and a Plasma 6 wayland session.

Comment 8 Noah Davis 2023-09-25 05:59:34 UTC

It seems to be some kind of issue with deselecting a text annotation action while clearing all annotations. This occurs when a new screenshot of any kind is taken. Technically, a rectangle capture screenshot first captures all screens, then allows you to crop the screenshot of all screens, which is why spectacle crashes when starting a rectangle capture screenshot rather than when accepting a selected region. Shortcuts are not necessary to reproduce this bug, but are a convenient for reproducing it.

The true steps to reproduce this bug are the following:

1. Do a screen capture of any kind using any method, but don't use the -i or --new-instance flags if using the terminal.
2. Add a text annotation without causing the annotation to lose the dotted outline it has while it's still considered selected by the annotation system.
3. Do a screen capture of any kind using any method, but don't use the -i or --new-instance flags if using the terminal.
