A number of weeks ago, I reported this problem on freebsd-ports: -------> Viewing large images has become cumbersome with the switch from Firefox 18 to 19. Am I the only one to notice this?
Wikipedia's high-resolution pictures of the day are great for this: https://upload.wikimedia.org/wikipedia/commons/e/e9/Bison_skull_pile_edit.jpg What happens is that Firefox loads the image and then does some sort of operation that causes the X11 server to be busy for a noticeable amount of time. During this time the whole X11 session hangs. If you have a network login, you can see the Xorg process eat all the CPU it can get. The duration of this delay varies and depends on the size of the image; with the one above it just took 30 seconds. This isn't entirely new. With previous versions of Firefox it happened when I accidentally dragged an image. But now with Firefox 19, just viewing the image is enough. Needless to say, this is painful if you are going through a number of large images and are forced to pause for half a minute each. <------- Unsurprisingly, several people have now run into the same problem on OpenBSD. Workarounds are setting MOZ_DISABLE_IMAGE_OPTIMIZE=1 in the environment or disabling gfx.xrender.enabled in about:config. (You have to restart Firefox after toggling gfx.xrender.enabled.) I'm throwing this out there, but users shouldn't really be required to invoke magic incantations. -- Christian "naddy" Weisgerber na...@mips.inka.de
