I don’t know that only happens to me or everyone but when I start to select the tabs with mouse, a strange thing is happening.
In a tab;
0% - 50%: tab is selectable
51% - 99%: tab isn’t selectable
100%: tab is selectable
This is what happens in Sublime:
And this is what happens in Atom:
It happens in safe mode, too. And I guess when I first installed the Atom 2 years ago, same thing was happening, too.
