Subject: bug#69784: 29.2; Proced auto update should only update visible buffers

From: Rahguzar <[email-masked]>
Date: Wed, 13 Mar 2024 22:00:17 +0100

Dear Emacs developers,

I use proced with 'proced-auto-update-flag' set to 't'. Often I quit the
window showing proced buffer and later some profile shows that the timer
used to update proced is taking a big chunk of time.

Since updating the proced buffer is a somewhat expensive operation, I
think the update should happen only if a proced buffer is visible.

I can send a patch to that changes 'proced-auto-update-timer' to this
effect.

Thanks,
Rahguzar
