Public bug reported:
I have a couple of applications that I wrote myself. They are OpenGL
graphics applications. One application uses SDL for OpenGL context
management, and the other uses GLFW.
When I resize the windows of these applications by dragging the window
edges, gnome-shell crashes almost 100 % of the time after a certain
amount of resizing back and forth. This does not happen when instantly
resizing the window (e.g. with Alt+F10, which effectively does a resize
as far as SDL and GLFW are concerned anyway).
Rapidly resizing the window of glxgears does not seem to crash gnome-
shell, which confuses me. I guess it is interacting with things
differently or something.
Anyways, I'm using the following versions of involved software packages:
gnome-shell: 3.2.1-0ubuntu1.1
nvidia-current: 290.10-0ubuntu1~oneiric~xup1 (from the ubuntu-x-swat PPA)
SDL: 1.2.14-6.1ubuntu4
GLFW: 2.7.2-1
I'm thinking that maybe the two libraries I use (SDL and GLFW) create
new OpenGL contexts every time when using their respective resizing
mechanisms, whereas glxgears does something different, and requesting
new contexts with new sizes too often during a small period of time
might not go too well? Not sure at all what details I can provide
regarding this problem. Hopefully someone can ask the right questions
and I will be able to provide the necessary information.
I will be very lucky if the applications were started from a terminal.
That way the undecorated window of the terminal has focus after the
crash, and I can relaunch gnome-shell from there.
Any help is appreciated!
