I know this section is about Gameplay Bugs, but the Diretide sticky is on here, so I'll post it here anyway.
If it needs to be moved, then it will be.

The Play tab on the Dashboard has been changed to include the new "Find Diretide Match" option, which has brought some visual problems along with it:



The black background thing behind the Matchmaking section is slightly too wide. It looks ugly.
Private Games section is missing the black background thing as well as the red boder.

Pure cosmetic. No impact on the Gameplay at all.
