Tech issues at VALORANT Champions 2026 in Shanghai stemmed primarily from metal components in custom stage desks interfering with wireless mice during the group stage, triggering multiple pauses and input problems in matches such as FUT Esports versus 100 Thieves. Riot implemented temporary wired-mouse requirements, then replaced the desk tops with non-conductive materials by early October, after which officials confirmed no further disruptions in subsequent checks or games. Playoffs began October 7 under the updated setup at Jing’an Sports Center before shifting to Mercedes-Benz Arena for the final weekend, with no reported mouse or hardware problems in upper- or lower-bracket matches. The remaining best-of-three and best-of-five series among LOUD, Team Vitality, 100 Thieves, and G2 Esports occur after these hardware changes, reducing the likelihood of additional technical interruptions.
