Hi, My program uses multiple QOpenGLContexts and a Quick context. It crashes predictably with a SIGABRT and the following message:
../../src/xcb_conn.c:186: write_vec: Assertion `!c->out.queue_len’ failed. This bug ( https://bugreports.qt-project.org/browse/QTBUG-31935 ) seems to be the same. Neither of the proposed solutions (calling XinitThreads(), or patching libxcb as directed, or both) solves the problem – the patched version just causes a segfault down the line instead of failing the assertion. The bug is closed (because it’s not a Qt bug) and the only relevant bug in xcb is similarly closed (they don’t think it’s xcb’s fault either). The problem only appears to occur on my laptop (using integrated graphics / mesa gl), all on Ubuntu 13.10. Any help would be appreciated! thanks, peter _______________________________________________ Interest mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/interest
