Subject: bug#17392: 24.3.90; cursor blinks faster and faster
Date: Sat, 03 May 2014 03:44:18 +0200

Hello,

sometimes when I work with Emacs for a longer time, the cursor blinks
with a very high frequency.  When I look at the value of
`timer-idle-list', I see multiple incarnations of blinking timers, like
here:

([t 0 0 125000 t show-paren-function nil idle 0]
 [t 0 0 500000 0.5 blink-cursor-start nil idle 0]
 [t 0 0 500000 0.5 blink-cursor-start nil idle 0]
 [t 0 0 500000 t
    #[0 "\205\301 \207"
        [eldoc-mode eldoc-print-current-symbol-info]
        1 "\n\n(fn)"]
    nil idle 0]
 [t 0 0 500000 t jit-lock-context-fontify nil idle 0]
 [t 0 0 500000 t which-func-update nil idle 0]
 [t 0 0 500000 0.5 blink-cursor-start nil idle 0]
 [t 0 0 500000 0.5 blink-cursor-start nil idle 0]
 [t 0 0 500000 0.5 blink-cursor-start nil idle 0])

The only related settings in my .gnu-emacs are

   (setq blink-cursor-blinks     0
         blink-cursor-interval .15)

I grepped through all my Emacs related files, including installed
packages, and found no more matches for "blink-cursor".

I have no idea what actions trigger the bug.

Reading the sources in frame.el, I don't see how having multiple idle
blink timers can happen at all.  Mysterious.

Hoping anybody has an idea or is seeing that too and can provide more
info.


Thanks,

Michael.
