Summary0012108: Hang when resizing window with text
DescriptionThis one is really hard to track down, but I think I have a case that replicates.
ParaView 3.10.1. Local client is Linux, remote server is Mesa. Mesa version seems to have this problem with 7.4.2 and 7.10.2. I replicated it with 7.10.2. I am using 16 pvserver processes.

Default settings (I believe). One thing I did do is change remote rendering size to 0.

Open 32 file Whipple Shield. All variables On. Apply.
Sources/ Text. Apply.
Make sure that your window can be resized (i.e., isn't full screen.). Now, grab the window at the bottom right and drag that corner up and left. Drag it back where it was. If necessary, go back and forth.

Within one or two itterations, it will freeze, without dying.

Upon killing the server, the client prints out that the server connection has closed, followed by the following line:
VTK/Parallel/vtkSyncronizeRenderers.cxx line 617
Only 3 or 4 component images are handled.

Server death output looks as follows:

I don't have either in a debugger, but could fairly easily if desired.


This is a showstopper for us. If possible, and if found, I would take a patch to apply on the 3.10.1 release.

 I tried tonight to replicate this bug with hardware OpenGL on the servers, and could not. Thus, I suspect it is some interplay with Mesa.

The problem versions of Mesa are 7.4.2 and 7.10.2. ParaView 3.6.2 - and Mesa 6.4.2 (I believe) worked fine. Not sure if it was a ParaView problem or Mesa.

 It is significantly harder to replicate, but it can be done with one remote server. Just keep moving the window size, drop it, pick it up, repeat. Should crash within a fraction of a minute.
