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?
Created attachment 87171 [details] backtrace
backtrace is lacking debug symbols, but it shows enough to say: switch window decoration, use Oxygen.
probably very relevant for debugging: which Qt version are you using (exact hash of qtdeclarative module might be needed)
Using Qt 5.3.0 release. Should I get a new backtrace with Qt debug symbols?
Actually it's 5.3.0 + this patch https://qt.gitorious.org/qt/qtdeclarative/commit/009ad875f89d7d7bc4447e18c2fbbd485a75e0b5
(In reply to comment #5) > Using Qt 5.3.0 release. Should I get a new backtrace with Qt debug symbols? 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).
