Hi,all Thanks for your messages,though most of them are out of my knowledge.
Some explanation of my original message. What I mean server-client is not the paraview server-client mode,but just run paraview on another machine(PC) and tunnel(or forward X11) the display on the local machine. Using this method ,I still get the bad legend. If I run paraview directly on the PC and display it on that machine,it's ok. If I run paraview in a virtual machine on my laptop,it's also ok. I also have tried to build VISIT on my laptop,and I got the same problem as paraview,the messy legend. I do not have any problem with my intel graphics card till now for other applications.The system now is FC10 with latest updates. Best wishes. -- 在2009-09-28，"Utkarsh Ayachit" <[email protected]> 写道： >Well, don't forget the scalar bar needs to be rendered for tile >displays.
