[Bug 1051231] [NEW] on creating main window X gets unusable, memory consumption gets overly high, high I/O-Load

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

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.

Same here, tested with Calibre and bzr-Explorer. Last time this two
applications crashed with this kind of failure it was because of python-
qt4, if i remember right.

This bug is happening with any python-qt4 based applications, and I
believe apport is publishing the bugs at the python-qt4 based
applications instead of here.

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
