[Solved]shortcut always delay 10-20s

[double_crane]

the situation is :

I set shortcut in gnome-control-center----->keyboard----->shortcut---user-defined-shortcut....and several months ago, it's OK,no delay after click shortcut buttons. but about one or two months ago,when I update some software (which I don't know, I did emerge -uDN world), it delays 10-20s after I click the keys, everytime .

the system-defined shortcut won't delay. only the user defined shortcut will delay .

I remember I met this question last year. I tried to solve but no way. some time later after one update ,it recover.

I have one laptop, one desktop computer. both Gentoo x86_64. but desktop don't meet this question

So, how to solve this ? thank you

Update gnome-light-3.12 to 3.14

now it's OK.No delay again

but still don't know which package cause the problem.

it has happened twice.
