Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace.

I'm afraid that reporter can't provide a backtrace with debug symbols. There is no debug packages in Arch Linux. I only submitted because the crash dialog said it could be useful. But I could try compiling with debugging symbols if it's needed. (In reply to Jesus from comment #3) > I only submitted because the crash dialog said it could be useful.

Here's how you can get KWin with debug symbols: * download PKGBUILD from https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/kwin * add -DCMAKE_BUILD_TYPE=RelWithDebInfo to the cmake command line arguments * run makepkg -i (if brave enough and don't want to add gpg keys, add --skippgpcheck) * after you submitted a backtrace with debug symbols, run: sudo pacman -S extra/kwin Maybe we should close this bug, since I don't know when it's gonna crash again haha. Crash is in
if (isTransformed())
qFatal("Splitting quads is allowed only in pre-paint calls!");
if it was the assert above we wouldn't see QtCore in the stack, if it was QList out of bounds, we would see two.
Also it makes sense as we are quite clearly in paintWindow which is post-pre-paintWindow
Working backwards frame 10 can only be:
SceneOpenGL::Window::beginRenderWindow
(line 1193)
which from the comment in the code
"// split all quads in bounding rect with the actual rects in the region"
which seems to go against the text of the other assert.
However, I can't get a transformed quad when trying to reproduce.
Jesus, can you post your ~/.config/kwinrc

I was able to reproduce KWin crashes when switching virtual desktops while a the "minimize" animation ("magic lamp") was being displayed.
That is: minimize a program on one virtual desktop and while the animation is displayed switch to another virtual desktop
*** Bug 396297 has been marked as a duplicate of this bug. *** It happens because some effects transform window quads(e.g. Fall apart or Magic lamp). So, when makeSubQuad is called on a window quad that has been transformed by Magic lamp for example, makeSubQuad will abort. Even though this bug has nothing to do with the Desktop Grid effect, 368847 and this bug are caused qFatal in makeSubQuad. If 368847 gets fixed, so this bug gets fixed. *** This bug has been marked as a duplicate of bug 368847 *** |
