Subject: 25.0.50; When font size is temporarily increased Emacs is slow
Date: Thu, 10 Sep 2015 15:56:46 +0600

When I press ‘C-x C-=’ to temporarily increase font size Emacs is
getting considerably slower. For example, if I hold ‘C-n’ to move
several lines down the movement is not smooth. I don't think that
increasing of font size should normally result in such “effects”.
