I recently downloaded Paraview 4.3.1. Whenever I change the size of the window the program will crash and state 'qtwidget: recursive repaint detected'. I realize that this must be an issue with qt runtime but I am unsure how to fix the problem. Any suggestions would be greatly appreciated.

Quick questions:

1. What Operating System are you using?
2. How are you launching ParaView?
   • Namely from a GUI or from a command line?

I am using Windows 7 and launching from the GUI.

I also have a Linux machine with the same version of Paraview. Everything works just fine on that.

Quick question: Do you have another Qt version globally installed in your system?

To check, start a new command line window and run:

echo %PATH%

if it shows a path for Qt somewhere in the output, then that's possibly why ParaView is having issues, since it might be trying to use an incompatible Qt version.

Another check is to run:

where QtCore4.dll

You may be on to something here. Yes I do have another Qt version globally installed. I use it with MIKTEX 2.9. Is there an easy way insure that Paraview will reference the Qt version that I installed along with it rather than the other Qt version?

The only way I know is to rely on a batch file for launching ParaView. Create one wherever you want, for example with the name "ParaView.bat" and place the following content inside:

@echo off
set PATH=%WINDIR%;%WINDIR%\system32
C:\Program Files (x86)\ParaView 4.3.1\bin\ParaView.exe

You might need to adapt the path for ParaView.

Update: I have now tried uninstalling MIKTEX (where QtCore4.dll now finds no files) and Paraview and reinstalling just Paraview. The problem is still persisting.

Please try the latest ParaView version, 4.4.0 RC2, which was released a few hours ago. With any luck, this issue is already fixed.

The issue persists in 4.4. However, I have resolved the issue. I have a program on my computer that launches at startup "DisplayLink" which allows me to use an additional monitor. When turned off, Paraview functions properly. I very much appreciate the assistance that you provided me.
