I have this same issue, Civil 3D labels only. I've attached some screen caps. The correct display pic is the way it's appeared in previous releases for me. I even tried changing the background color in MS to white, same result.
I have opened an SR with Autodesk 07479109
Label backgrounds turn white. PITA.
Thanks for anything you can come up with.
This is a know issue that our Dev team is working on.
The current workaround is to uncheck “display plot styles” in the Page Setup dialog.
Hope this will help.
Alright, my guess is that this happens with people who are using CTB files but not STB files. I have been pulling my hair out because I had been trying to change all the variables that could remotely be related to the display and NONE seemed to be controlling the masks in Civil3d objects. Since they show up correctly with show plot display off, it should have occured to me that the plot style tables were the culprit.
So what is happening - The application is using PEN NUMBER 7 (which was the white pen) for the mask. Screening does not affect it, but the sole variable it draws from is object color. So simple thing to do? Just make the object color white, or if that goes to black set it really close to white.
THe biggest problem with this is I rarely know of a company that does not use Color 7. The appropriate behavior for Civil3d Background masks would be for it to pull the variable for the actual background color. This should be an easy fix - Autodesk, please make a hotfix for this! In the meantime, what we have found is that we can set the color off-white but with pretty heavy chroma (like red or blue) and set the screening to about 50%. All the masks are a bit darker, but the text underneath is barely readible.
Although this is not a fix, it's a work around. We are unable to use this work around in our environment, so we're waiting for a hotfix or SP to implement this version.
I noticed the same thing happening and just chalked it up to another bug in 2013. Glad to see I'm not going crazy.
BTW, has anyone had any problems with the match line mask being solid black even when the color is set to 255 while using the default monochrome.ctb? I had to make the mask color #254, create a copy of the monochrome.ctb, and set color 254 to plot white. This was the only way to make the C3D match line mask in paper space not plot solid black for me using the default monochrome.ctb.
