Title menu icon doesn't look good while hovering

I noticed the background of title menu icon changes while hovering it.
The behavior is different from the one of other icons.
Is this happen only for me? Looking for help

Welcome to the Hookmark Forum , @hahanbyul . Thanks for the feedback. That’s by design. We wanted to draw users’ attention to this button because it contains the most important commands. We’ve tried various thinks in the past.

In Hookmark 5 not yet in public beta, we’ve removed that effect.
