Hopefully, this is the right place to ask... if not I apologize.

Ever since this morning, my keyboard would randomly start to lag when typing in the game's chat, it started gradually and it has now reached the point where I need to input a character 4 or 5 times before it reads it or I even need to click out of the chat for a few seconds before I can finish the sentence.
It happens only there, the keybinds on hotbars, movement and general shortcuts all respond well and I had no issues playing, as long as I didn't try to say anything in the chat. Same way, I tried out every other software and place that allows text input that I could think of but didn't have this issue (and this post is sort of a testament to that). I've been experiencing a few connection issues lately (problems with our provider) but as I could generally move around and do things even in raids while I couldn't type properly even in desert places like Azys Lla, I don't think they're related.
Logging out seems to solve it for a few minutes, but then it starts again.

I tried to google around to see if I could find anything of use, but most of what I found involved either people playing on PS4 or using an external keyboard (it mostly seems to be a Logitech hardware thing) and I'm playing from a laptop (been using it for the last year and had no issues aside the occasional black screen on log-in) and using its own built-in keyboard, so I'm a bit at a loss on what to do.

Thanks in advance for the help
