From: Anders Waldenborg <anders <at> 0x63.nu> To: bug-gnu-emacs <at> gnu.org Subject: 23.2; Pixmaps kept in X11 after (svg?) images no longer are used Date: Thu, 20 May 2010 17:40:30 +0200
By running the command defined by the following:
(require 'cl)
(defun aw-replace-buffer-contents-with-svg-images ()
(interactive)
(erase-buffer)
(dotimes (N 200)
(insert-image (create-image (format "<svg width=\"50\"
height=\"50\"><rect x=\"0\" y=\"0\" width=\"100\" height=\"100\"
fill=\"#%02x%02x%02x\"/></svg>" (random 255)(random 255)(random 255))
'svg t))))
the current buffer will be replaced with 200 images. Running xrestop it
can easily be seen that 200 pixmaps are added to the X11 server every
time the command is run.
One would expect that the pixmaps were removed from X11 when they don't
exist in any buffer any longer (which is why recipe uses erase-buffer so
it can be run multiple times, increasing number of pixmaps every time -
not the behaviour I expect).
The pixmaps doesn't even go away when the buffer is killed.
Don't know if this applies to all image types or only svg.
