Xwin32 is the name of an X-server product for Windows that lets you display back from remote machines over X11 to your local Windows computer. With its default settings, Xwin32 tends to have some difficulties with OpenGL applications such as VisIt. This is one reason we stress that you should not use it.
We instead hope you consider installing the Windows version of VisIt on your local Windows computer and run client/server if you need to access data on a remote computer. This offers the following benefits:
- Your gui button clicks won't have to go over the network so interaction will be better
- You are not relying on any buggy X-server for your windowing and OpenGL support
In the event that you need to run an X-server on Windows, we'd instead recommend the X-server bundled with Cygwin since it seems to have better OpenGL support.
If you must use xwin32 then try these steps to configure it to work better with OpenGL applications such as VisIt:
- Open the XWin32 X-Config
- Go to tab Window
- Check OpenGL software rendering checkbox
- Click Apply button
