Uncontrollable keyboard shaking when using Apple Pencil on iPad

When using my Apple Pencil to write on my iPad, the keyboard sometimes pops up in the corner. All of a sudden it's begun shaking uncontrollably for no apparent reason specifically when I press shift, open numbers or try to switch between language keyboards. I've tried everything I could think of in settings but nothing seems to be fixing it. Any help would be greatly appreciated.
