line problem

[domer1322]

can anyone explain why I frequently get the tiny white lines in my OpenGL renderings as shown on the attached image ?    I put purple boxes around them.  At first I thought maybe they were layer page boundaries, but realized they are a grid, not a rectangle.   They also show up on printed paper, but they are so thin they they are not a critical problem.

Check if you have Show Grid and Print Grid turned on in the snaps.

thanks for the response, but it didn't make any difference.  The lines show up on the design layer, but the image I sent was from a sheet layer viewport.  IN both cases, changing the 'print grid/ show grid' boxes didn't matter.  The lines do not show up in Renderworks (fast nor final) and they don't show up in hidden line rendering.  They show up in OpenGL if I render with colors or textures, or without.  Setting the OpenGL setting to low detail (or high detail) makes no difference.  I don't have the guide class or 'non print' class on.

 

Anyone have another idea ?    .....    or can anyone else tell me if they noticed this ... or am I the only one having this issue ?
