Network Profiler UI is broken

I’m trying to reduce the lag in my multiplayer game, so I recorded some data with the netprofile command and opened it up with the network profiler to see what I could improve and reduce the lag (I assume this is the correct thing to do). However the UI is broken

This makes my life quite difficult. I’m working with the engine source code so I figured I’d go look at the code and see if I could fix it. But I can’t seem to find the source code for the profiler.

To be quite frank, what do I do now?

EDIT: I’m on windows 10, if that’s relevant.
