the version on this web page works fine, but the exe sends itself really fast random inputs when my controller's plugged in. i've tried both exes and i'm not sure what's wrong with my switch pro controller :/
good tool
if you're not busy, can you try running this and let me know if it still does the input spam? its the HTML version but for desktop~ https://moonspod.itch.io/input-display-test/download/6I_NRUK0vGNkISB1_iW7R2UEy6Q...
aah i really dont know why this is happening, it sucks, try one last thing, grasping at straws, there is another download for an fps locked version https://moonspod.itch.io/input-display-test/download/VhOznDZIN3XO8bceLF47pSxPATd...
if this doesnt work, which i doubt it will, i wont be able to help sadly, sorry
