Please describe your issue in as much detail as possible:

The chat that is embedded below ready confirmation is cut in half sometimes when matchmaking found a match. My screen resolution is 1680x1050, just for case.

Steps for reproducing this issue:

1. Try to find a match through Competitive Matchmaking.
2. Wait for it to ask you to ready up.
3. Look below the box.

Still not solved, and it persists if the match is canceled (happened to me yesterday):

Using a laptop on Linux

This seems to happen if the social slideout thing on the right is open when the match is found. Just happened to me today.
