What are hidden red flags that are hard to catch?

Like red flags you only see after you get to know somebody

It's really hard to tell. You will have to read between lines. I personally wouldn't like someone who is
- arguing so much,
- taking the dating/relationship a little lighter than it should be,
- bragging about having had too many dates/guys hitting on them etc,
- speaking so highly of them all the time,
- never admits a mistake/wrongdoing,
- trying to take the upper hand by manipulation,
- lying or bragging about lying
- bragging about manipulating

In the beginning, all of these will be hard to detect as those are not expressed on a bigger scale. So you will have to keep your attention to detect them.

PS: Just listed things that my ex did. (before and after get to know her)

Compulsive liars.
Needy/clingy.
Backstabbing.
Sociopathic (not psychopathic).

Usually takes time to see these in action.

Red flags are never hard to catch, they are always extremely obvious but some I will say are anger management issues, laziness, stinginess, an inability to make correct logical moral choices, a preoccupation with circumstantial material conditions, anger when expectations are not met, perverse or nonsensical sexuality, dishonesty and disrespect for weak people, a willingness to bolster you status at the expense of others, a refusal to be fair or considerate when your in a bad mood, a desire to belittle weaker woman or men, a refusal to give people a chance when they are different from you, obsession with race or culture or ideological religious rituals, or a refusal to be kind to people based on personal bias.
