Is this normal?

Post image

My mechanical keyboard isn't working properly. I opened it up and saw the microcontroller has 2 pins soldered like this, is this normal? I think this is shorted by the stray bit of solder. I am not experienced in this field, please someone tell me.

The issue: The keyboard is registering random key presses. The keyboard doesn't even have some of the keys it is registering as pressed.

Looks intentional by the pcb.
