Everything in the top bar is stretched and weird looking, here’s a screenshot:
It’s been like this since version 3.5. At one point I just ignored it but I’ve been working on a huge project in the last couple of weeks and it’s been driving me up a wall. On Windows 7 64-bit.
Edit: Here’s a more complete screenshot: http://puu.sh/43UKX.png
Edit2: I should mention there’s tons of that stretched whitespace in everything, not just Writer.
