bug#24339: 24.5; Need double c-g to quit from a minibuffer

[Yujie Zhou]

Dear Emacs maintainers,

on this device I need double pressing C-g to quit from a minibuffer, 
even starting from 'emacs -Q'. More specifically, after pressing C-x 
C-f, if I do not realease the control botton, I only need one C-g to 
quit the minibuffer. But if I realease, I need two. If I only press C-g 
once, the minibuffer shows the text quit, but the cursor is still 
focused on the minibufer, and I have to press C-g again within 3 
seconds, otherwise the Find-File minibuffer reappears after the text 
quit fades in 3 seconds. And in that case, I need to double-press again 
to quit.

You've mentioned at http://emacs.stackexchange.com/a/26715/5296

    I solved this myself by switching off the option of Show position of
    pointer when the Control key is pressed in Linux mouse setting. I
    guess there is some conflict between Emacs and this option.

so it seems some OS feature might be modifying the keystrokes that Emacs
sees.  Can you show the contents <f1> l (view-lossage) after you've hit
C-g with this option on?

Ok, looks like Emacs isn't seeing the keystrokes at all. Is it like
that for every key combined with ctrl, or just C-g?

What kind of system is this on (GNOME, KDE)? Maybe the best we can do
is add a description of the problem to etc/PROBLEMS.

Okay, I found this is a known bug of Cinnamon.  Closing since it's not
an Emacs bug.
