Text overlapping - but not always

[midana]

Sometimes some texts overlap and some text go outside of it's div. I see no apparent pattern to it, it's p, span, li and a - the only incommon thing is that I see it on texts.

 

One weird thing is that when I open Chrome developer tools it goes back to normal right in front of me - without me changing one thing. 

 

Anyone had this issue or know what is causing it?

 

Here's how it looks when it's overlapping.

 

 

And here's how it looks when it's normal:
