I am working on this - when saving out animations the representations of the chart are never updated. I am just digging through the animation framework to determine the correct place to ensure this happens for charts.

Nope, not at all good. This now causes a crash that brings the X server down.

Mind you, the crash I have is with exodus.

Note: I tried it with a local windows build, and it didn't crash.

I replicate it as follows:
ParaView, trunk, local server, Linux.
ssh -X into a Linux box.
Open can.exo. All variables on. Apply.
Plot over line.
Save Animation. Save as .avi.
Crashes and brings the XServer down within a few frames.

I am not entirely clear - you are running an X server on a remote Windows system, or a remote Linux system? I will attempt to replicate, but I have not tried running in this configuration. Is this just when trying to save an animation, or a general problem with 2D charts bringing the X server down?

So, forwarding X from master Linux over to a Mac I am able to produce a hang. It is actually in vtkTextureObject.cxx (line 265), where a required OpenGL extension is not supported by the context. I suspect the crash you see if also something to do with OpenGL extensions, if you let me know the X server/OS I will try to reproduce and get a backtrace.

Sorry, I didn't see the previous question.

Thanks, I am able to reproduce. It is an issue with OpenGL extensions on the X server being forwarded to as far as I can tell. When I disable text rendering I get an initial render, but still see a crash on the next render. This is a separate issue to the one reported in this bug as far as I can see - it is a general issue with the charts, and OpenGL extensions on forwarded X sessions. I will have to resume debugging this on Monday as I am not in the office Friday/over the weekend.

I have opened a separate bug report to track this issue, bug 11047. The histogram animation issue is resolved, but there is a general issue with the 2D charts causing a hang/crash when ParaView is forwarded over SSH to a remote X session.

Fixed. Tested trunk, local server, Windows.
