Binary package hint: gdm
Some apps are experiencing issues where memory usage grows wildly when
scrolling in a window. When the total system memory usage grows close to
100%, the app I am scrolling crashes and the memory it once consumed is
returned. Top reports memory belonging to Xorg.
Here is some data about my system:
* 4GB of memory, only 10% in use after boot and launching normally used apps
* Kernel is linux-image-generic-pae (although at the time of the bug filing I
am using linux-image-generic to see if PAE was the issue)
* Using Gnome desktop, and problem exists with or without compositing enabled
* All software is up-to-date as of the time of posting
* NVidia GeForce 7300 LE, running dual monitors via TwinView
To reproduce, I open gnome-terminal, do something to that generates
enough output to scroll the window, move the scroll bar up and down
repeatedly, memory grows, then it appears to fill physical memory and
then gnome-terminal crashes and then memory is recovered. Under normal
use, it happens in gnome-terminal or Eclipse Galileo within a few hours
of working (I'm a Java developer), and is EXTREMELY frustrating. This
also happened when scrolling in gedit and evince. It did not happen when
scrolling in firefox, gvim, or open office.
A workaround for an unrelated issue with Eclipse to fix an issue with
dialog display resolves the scrolling/memory problem. The workaround was
to set the environment var GDK_NATIVE_WINDOWS=1, which disables client
side windows. This workaround also resolves the scrolling/memory
problem in all other apps when set properly.
Although I have a working workaround, the bug still exists.
