Strange issue with camera moving, dialogue skipping and target swapping

Hello

I've recently been experiencing problems while playing FF XIV where sometimes the camera angle will begin to move when i move my mouse (while i'm not holding any mouse button down), sometimes when reading dialogue it gets skipped through automatically without me touching any buttons and finally sometimes during a fight my target will automatically de-select or aim at a random other mob.

Naturally I began to think there was an issue with the mouse i was using (Razer Naga 2012 model) so after taking it apart and cleaning it and the problem still persisting I decided to buy a new mouse which i am now using, however the issue hasn't gone away. So after this my next assumption was of course that the keyboard was the issue, after cleaning the keyboard and making sure the keys were also clean underneath i started the game again to find that this problem is still happening.

Is anyone else having this issue? Or does anyone have any ideas of what could be causing this and how i might go about stopping it? It's so annoying for someone who actually enjoys reading the dialogue in the game!

Any help is appreciated, thank you!
