Recent technical disruptions at VALORANT Champions 2026 in Shanghai have centered on wireless mouse interference from conductive metal components in the custom stage desks, triggering repeated input stutters, missed shots, and extended tech pauses across group stage matches. The most prominent incident occurred September 30 in FUT Esports versus 100 Thieves on Split, where four pauses interrupted play and a weapon malfunction went unrolled back. Riot identified the desk material as the root cause, applied temporary fixes, mandated wired mice for remaining group stage matches, and began installing replacement desk tops on October 2 with plans to test wireless options. A October 1 update from global esports head Leo Faria noted improved stability aside from minor audio glitches. With playoffs scheduled to begin October 7 in a double-elimination bracket, the extent of any lingering hardware or production issues will determine pause volume in the higher-stakes series.
