Bug 512376

SUMMARY

Similar to the existing "Disable [touchpad] while typing" feature, accidental mouse input can cause issues when gaming (depending on the game, of course). Specifically, games tend to switch to a "keyboard + mouse" mode when they detect a mouse input, causing gamepad input to be ignored until a new input from the gamepad is received (i.e. moving the stick), causing the game to go back to it's "gamepad" mode. This is very noticeable with games where you have your stick in the same non-resting position for prolonged periods of time, where for example, a micro-movement in the mouse could cause you to stop moving in the game, which can be a big issue.

SUGGESTION

What I suggest is that if KDE Plasma detects that a gamepad's stick is in a non-idle position (respecting deadzones) or a button/trigger is held down, input from any connected mice are ignored, to prevent this issue. This feature should be optional however, as this might cause unforeseen issues for some people.
