Maybe its just a situation with too many keyboard commands. New keyboard or you never noticed it before because of your toggle?

There is a simple keyboard test I found a while ago:
press both shift keys and write the standard sentence: THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG


My Logitech G510: THEQUIKBROWNFOXJUMPSOVERTHELAZYDOG
No spaces and C is missing. Thats why I canīt do trickjumping.
