Lets follow this at > https://crash-reports.kde.org/organizations/kde/issues/203684/ > ?project=12&referrer=project-issue-stream Hello David, I'm unable to access the page you linked (unless it's meant for other developers? I apologize, I'm new to this), but are there any other details I can provide that could help you, like the trace from Krita's subsequent crash (immediately after the one I posted)? Thank you for your work 2440128 3 vlad.zahorodnii 2025-07-11 11:13:08 +0000 How did you make kwin crash? 2440130 4 albi670.ac 2025-07-11 11:19:12 +0000 (In reply to Vlad Zahorodnii from comment #3) > How did you make kwin crash? It happened in three separate instances across 6.4.0, 6.4.1, and 6.4.2 on wayland; in all three instances, seemingly at random, while I was drawing on krita with a huion new 1060 plus tablet with a youtube video playing in the second screen, kwin crashed and took every other program down with it before restarting on its own. 2440140 5 bug-janitor 2025-07-11 11:55:35 +0000 A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/7904 2440148 6 vlad.zahorodnii 2025-07-11 12:20:29 +0000 Git commit 6489b0ab8217431f239805705107e3d9178c35ee by Vlad Zahorodnii. Committed on 11/07/2025 at 11:53. Pushed by vladz into branch 'master'. Guard against internal window being null when dispatching tablet events Tablet focus updates can be blocked while the tip or a button is pressed down. If an internal window is closed in meanwhile, kwin may crash due to dereferencing a null pointer.
