Finlay Knox won his first world title, and Canada men's first since 2007, at the Doha World Championships in the 200 IM. We saw many backstrokers in Doha hitting the lane line during their races and Knox explained that the ceiling wasn't straight, so the competitors swimming backstrokes were not always swimming in a straight line. Knox explains that he got lucky by landing in lane 7 for the final, where a pillar was straight across the ceiling to follow during the backstroke leg of the 200 IM.
