Description

Looks like some shadow got deleted (through deleteLater) after the scene/effectshandler was destroyed. From the description through a updateShadow() from a removed client, BUT: this would imply that the deleteLater event is delivered to a destroyed object, because the SceneOpenGLShadow should be destroyed with Compositor::finish() *before* that deletes the effects and scene. => Can you reproduce this? I can, check out this fresh backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

New crash information added by DrKonqi
kwin_x11 (5.5.5) using Qt 5.5.1
- What I was doing when the application crashed:
Starting some steam games (mostly indie, linux versions) leads to kwin crash when the game switches to fullscreen. With those specific games (e.g. "J.U.L.I.A: Among the Stars") this crash happens on every launch.

*** Bug 363527 has been marked as a duplicate of this bug. *** Has this been fixed in kwin 5.6.x? I don't want to upgrade my distribution to the experimental branch just to check if it is fixed ... I just found that this bug has been fixed by https://quickgit.kde.org/?p=kwin.git&a=commit&h=cae90bb035e6170a9beb38545cf60e31af612804 which can be applied to kwin 5.5.5 without conflicts. So I guess this can be closed. Thanks for the backlink, update and confirmation =) *** Bug 365964 has been marked as a duplicate of this bug. *** |
