XF 2.2 Different size at new posts

[teletubbi]

Long time ago i wanted to ask this already.
Don't know why i always forget it.

If i choose new Posts i recognize that some of the threads have a different font size.
Thought has something to do with my custom style but i see it here, with the stock style, as well.



So just want to know why this is happened.

The difference is read and unread threads.

What you mean?
I haven't read any of the above threads.

It's a browser issue.

Browser issue - Title font difference on mobile?

Some titles have larger font. I clicked so you can see bold/not. Android
