--- Comment #2 from Holger <private_l...@yahoo.com> --- Created attachment 159147 --> https://bugs.kde.org/attachment.cgi?id=159147&action=edit stacktrace of the crash Thanks for the link - that was helpful, though it downloaded 720 GB of debug symbols. In addition, I found, I can also crash KWin by forcing a negative (x,y) position, e.g. to "hide" the window decoration by moving them out over the upper left corner off the screen. The setting is stored, but the dialog became invisible - likely it is shifted far off outside the screen and I cannot see it anymore (other than that it darkens the parent and blocks all input) - luckily I could close it by Escape. A position, that will shift some of the dialog out to the lower right is fine though. Only the upper left corner must stay on screen, while moving a window manually off screen by META+LMB-drag works nicely. -- You are receiving this mail because: You are watching all bug changes.
