OpenGL stability issue / freezes / Crashes


    Oct 04 2012 | 6:54 am
    Since a few weeks I have quite a lot of OpenGL crashes (MBP 10.6.8, Max 6.0.7)
    I'm not sure what causes them but it feels related to these posts:

    For me it happen mostly when opening Gl objects help file +/- copy/paste elements into the patch I'm working on.
    When I don't add/delete any GL objects, everything is fine.
    Symptoms:
    Freeze and/or very glitchy window output.
    Patche freeze, I can't save/edit/change mode.
    Message: jit.gl.fbo: unsupported framebuffer format.
    I don't have patch to demonstrate but I will try to make one.
    Does anyone has this kind of problems ?
    Thanks

      yes,
      it's the same thing as http://cycling74.com/forums/topic.php?id=42632
      but with me it's never fine, whith a few slabs in my patch everything tends to freeze and crash big time, most of the time this means restart the whole computer

      that's great news!!
      On a pure selfish note, I have a performance in 3 weeks, should I start addapting patches to get rid of all things slab/capture. Or is a fix on the horizon?

      i think these crashes are related to deleting jit.window or jit.pwindow.
      if you can describe another scenario where this crash occurs that doesn't involve deleting a opengl window, it would be much appreciated if you can provide a patch and instructions to reproduce.

      For me it's that: deleting a jit.pwindow or closing a patch with one in it.

      If we include "closing another patch with a pwindow in it", it is the case for me.
      The annoying point is that most of the help files have one ;)

      yes, should've been more specific.
      from what i've been able to determine, the crash results when you have a patch with some kind of texture object (jit.gl.slab, gl.texture, gl.node, etc), and you free a pwindow or window object (either by deleting or by closing a patch).
      thanks again for the reports, and we'll get a fix as soon as possible.

      just offhand posting in the few threads related to this as I find them (they touch on slightly different angles) - editing a patch w/ gl.slab + gl.texture (not just deleting or freeing windows) does it for me. thanks for your work on solving this!

      Exactly the same troubles and messages, but even without editing : just let run a patch w/ jit.gl.slab, jit.gl.node a few moments and it crashes !
