These don't seem aligned to me:

See my comment about the traffic lights being misaligned with other elements in the title bar.

idk looks fine on my end:

maybe this has to do with the ui_font_size setting

the traffic lights are in the middle of the title bar – also on your screenshot

on your screenshot it looks like the other elements are a bit too far up

[slymax]

nvm I moved them up a bit so they look more aligned with the default ui_font_size setting

The traffic light position should just be in the middle of the title bar, don't consider the text. Though you gotta think of the window border included as part of the title bar. Illustration:

If the text looks misaligned, the text itself would need to be moved (and in that case, consider the alignment of uppercase characters and other alphabets)

Looks better now!
