Try disabling the use of display lists i.e. turn on "Use Immediate Mode Rendering" from the settings dialog (http://paraview.org/Wiki/ParaView/Users_Guide/Settings). That may help with the GPU memory issue. We do release display lists when data changes, but maybe there's a driver bug or something that may cause the issue.
