Crash on neon unstable running on my laptop without any external screen too. Can you confirm https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/1873 and https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/1008 fix your bug? The bug is likely to be caused by "divide by zero" in ImageColors. . *** Bug 457742 has been marked as a duplicate of this bug. *** A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kirigami/-/merge_requests/721 Git commit 1337d3ffddd7e7ce563ecb14b1ad5730edc97a32 by Nate Graham, on behalf of Weng Xuetian. Committed on 12/09/2022 at 16:13. Pushed by ngraham into branch 'master'. Always reset m_futureImageData to null after deleteLater Two calls to ImageColors::update() in row may access a deleted m_futureImageData and cause crash.
