I have tried to like it for a while but I find it distracting from the actual (header) text in an active window. I really suggest to tone it down, or even remove it or make it a thin, solid but flat non-bloomy color. I also feel it’s a bit non-immersive. It’s a bit ‘gamer gear’ flashy.
Honestly I think removing the ‘bloom’ would probably already fix it. This goes for pretty much all the UI elements where there is bloom.
