This seems to be due to overlay-scrollbar. If you run it like: LIBOVERLAY_SCROLLBAR=0 picard it works fine.
** Summary changed: - on creating main window X gets unusable, memory consumption gets overly high, high I/O-Load + Picard freezes X when overlay scrollbars are enabled ** Package changed: python-qt4 (Ubuntu) => overlay-scrollbar (Ubuntu) ** Package changed: xserver-xorg-video-intel (Ubuntu) => ayatana- scrollbar -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1051231 Title: Picard freezes X when overlay scrollbars are enabled Status in Ayatana Scrollbar: Confirmed Status in “overlay-scrollbar” package in Ubuntu: Confirmed Status in “picard” package in Ubuntu: Confirmed Bug description: after starting a wireframe shows up, and then a high I/O-load occurs, memory is consumed up to 90%, X-Windows gets completely unusable (freezes), but changing to console (ctrl-alt-f1) is possible - 20-40s after pressing the keys - and instantly I/O-load drops to zero as switching to console happens. Therefore I think this may be a problem with QT or even X-Windows itself. There are some errors printed by picard/QT/X-Windows on the running terminal: (python:5103): Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion `GTK_IS_WIDGET (widget)' failed {Comment: dozens of that} QWidget::setMinimumSize: (/MainWindow) The largest allowed size is (16777215,16777215) {Comment: some of that} QNativeImage: Unable to attach to shared memory segment.
