Description Antonio Rojas 2014-06-13 17:50:13 UTC

Kwin locks up completely when closing some windows, the system stops responding to mouse and keyboard until I kill kwin from another tty.
It happens quite frequently when closing choqok (which closes to the systray), but I have seen it occasionally when closing other windows too
This started some 4-5 days ago. Currently using eb5abed

Reproducible: Sometimes

can you try to gdb into it when it happens?

backtrace

Comment 3 Martin Flöser 2014-06-13 19:38:45 UTC

backtrace is lacking debug symbols, but it shows enough to say: switch window decoration, use Oxygen.

Comment 4 Martin Flöser 2014-06-13 19:40:47 UTC

probably very relevant for debugging: which Qt version are you using (exact hash of qtdeclarative module might be needed)

Comment 5 Antonio Rojas 2014-06-13 19:43:30 UTC

Using Qt 5.3.0 release. Should I get a new backtrace with Qt debug symbols?

Comment 6 Antonio Rojas 2014-06-13 19:47:26 UTC

Actually it's 5.3.0 + this patch https://qt.gitorious.org/qt/qtdeclarative/commit/009ad875f89d7d7bc4447e18c2fbbd485a75e0b5

I don't think that's needed. I will try to reproduce it with latest Qt 5.3 branch (need to update to it anyway).
