I'm hoping someone can help me get rid of this checkerboard background. Not sure if it happened with the upgrade, but it is giving me a headache.
These are video rulers and so on.
To avoid them use another document preset ( no Video preset).
To remove them in existing documents see:
( sorry, screenshots from my computer in german language)
If that works for you
Thanks. I was able to get rid of the background pattern finally. The video rulers don't want to go away even when not chosen.
You can't turn it off or you don't want to turn it off? (My english is not the best, sorry.)
Another simple way to get a "clean file":
Creating a clean new print file did the trick. Thanks for your help!
As for the checkerboard: View menu > Hide Transparency Grid.
Like @Kurt Gold wrote before. If you only mean the checkerboard background grid. You can toggle on and off that in the view menu.
Note: The standard shortcut is [Shift]+[Ctrl]+[D]
Maybe you used it accidentally.
