Since commit bbe8a899ac91f93bcdb14fec8c200cd3f2256987 which increases the size of the icon 5 times, the visible bell has become way too big and distracting on the master branch: cf. attachments before.png vs. after.png on a full screen Emacs frame. To reproduce: emacs -Q -eval "(setq visible-bell t)" and trigger bell by pressing up key until it reaches top of buffer. Regards, Sébastien.
