Package: python-visual Version: 1:5.12-1.1+b2 Severity: grave Using VPython (python-visual in Debian) now always produces
i915_program_error: Exceeded max instructions For example, $ python /usr/share/doc/python-visual/examples/doublependulum.py i915_program_error: Exceeded max instructions A seemingly related problem is that the rendering is *very* choppy. The pendulum leaps roughly from one extreme to the other, without going through intermediate positions. This choppiness makes VPython nearly unusuable for displaying simulations. It shouldn't be so jerky and slow. The hardware is a Thinkpad T60 w/ Intel integrated graphics (945GM). Several years ago, on much slower CPU and graphics hardware, I didn't see this problem. That was with earlier versions of VPython and the X server, but I don't think VPython itself is responsible. There's a discussion on the vpython mailing list at <http://comments.gmane.org/gmane.comp.python.visualpython.user/3045> Rather, I suspect that hardware acceleration isn't working.
