I made sure there was no leaks.

Start with doing a "Check for problems" in Hammer (Alt+P) and fix any problems that might show up.

This problem can also show up if the map is too close to the end of the grid, if so, go "Map" ---> "Select All" and move the map closer to the center of the grid.

If none of above works you'll need to find the offending brushes manually (Ctrl+Shift+G) delete them and re-create them.
