Slider spatial unites

I am using the slider with spatial unites set to “from exp settings”, it doesn’t look well aligned with full screen mode:

However, for some reason, without full screen mode it looks good:

Is there a way to change this so slider looks well aligned in full screen mode? I tried changing spatial unites to “norm” instead, but it doesn’t seem to save the situation (also, I am unable to change the letter height).
