@bulletbuster2004 I'd like the whole deviceconfig, please. It's in in Documents > Electronic Arts > The Sims 3. You'll neeed to manually open the folders; the file won't show up in a search. You can delete your user and computer names, about 25 lines down, but there's nothing else in that file that can identify you.
@Zakaryski88 Same as above, please provide your deviceconfig.
@belleessie Did the lines disappear on-screen, or just in your screenshot? If the latter, then it's possible the issue is downstream of the screenshot function, for example if there were a problem with your screen itself, it wouldn't show up in the screenshots.
For the issue with hair, please click Me Too and post in this thread:

Since hair is affected for you, it would be helpful if you attached a deviceconfig in that thread as well.
