OpenGL accel seems to work, but some things cause asserts -> Fixed in SVN/3.1.6

[John Carr]

I'm getting this error on an OSX host with an Ubuntu Jaunty VM. Using 3.0.2 and 3.0.2 additions.

OpenGL Error: Assertion failed: !context->pOwnWindow, file /mnt/tinderbox/add-3.0/src/VBox/Additions/common/crOpenGL/context.c, line 894

This is code using clutter 0.8 and works on unvirtualised ubuntu. Apologies for the heavy clutter references that follow... This problem occurs if we use clutter_stage_new(), but not with clutter_stage_get_default().

Here's the test case:

#include <clutter/clutter.h>
#include <stdlib.h>

int main (int argc, char ** argv) {
    ClutterActor* stage;
    clutter_init (&argc, &argv);

    //stage = (ClutterActor *)clutter_stage_get_default ();
    stage = (ClutterActor *)clutter_stage_new();

    clutter_actor_set_size (stage, 800, 200);
    clutter_actor_show (stage);

    clutter_main ();

    return 0;
}

gcc -Wall -g test.c -o test pkg-config clutter-0.8 --cflags --libs

Irc tip, so i wouldn't forget it: Jc2k: yes, you just need libclutter-0.8-dev

[Leonid Lobachev]

Should be fixed in SVN.

[Frank Mehnert]

Please upgrade VBox to 3.1.0, upgrade the guest additions to 3.1.0 as well!

[Sam Morris]

I'm seeing this with 3.1.2.

$ ./test OpenGL Error: Assertion failed: !context->pOwnWindow, file /build/buildd-virtualbox-ose_3.1.2-dfsg-1-amd64-Yq77uy/virtualbox-ose-3.1.2-dfsg/src/VBox/Additions/common/crOpenGL/context.c, line 894

[Leonid Lobachev]

Fixed in SVN. PS. Not sure if this code is supposed to show anything though, as I only see a white window. If it's not expected output, open a separate ticket please.
