Subject: bug#29050: 26.0; Change in when `window-configuration-change-hook' is run
Date: Mon, 30 Oct 2017 09:24:50 +0100	[thread overview]
Message-ID: <59F6E1D2.1040302@gmx.at> (raw)

 >> 'window-configuration-change-hook' is a quite expensive hook which is

 > OK.

Closing this bug then.

Thanks, martin
