Tried this, didn't solve it. Does appear to calculate the right width though (when the text size is changed; not enough to trigger the axis change).

Thank you! Had to solve a similar problem for Android as well, which is where the "intercepting and modifying the request" idea came from. Thankfully I do not need to deal with chunked transfer encoding or persistent connections and the body always starts with a 0xD3 byte. The HTTP Just Kidding™ protocol is called NTRIP, made by RTCM and used by a lot of very large companies, for some reason. I would love to yell at them, sadly RTCM require paying a lot of money to even speak to them.
