Window resizing very jerky
In M8 window resizing was smooth and the contents would not be redrawn until the mouse button was released. In M9, when resizing a window, the contents are redrawn during the resizing.

The redraw during resize is a feature that we are evaluating. If people like it, it will stay otherwise we'll remove it. Closing as invalid. For information: what kind of build are you using (debug/optimized) and what is your machine (beige/blue, processor speed)?
I have been using the release versions of M8 and M9 on a blue&white 350MhZ running OS8.6. Because no other Mac browsers behave in this fashion and because surely this effect will be exagerated on slower machines I believe the 'non- jerky' resizing is favorable.
Thanks for your comments. FYI, I just noticed the following: if there is not a lot memory in the system heap and if the window is relatively large, the offscreen buffers cannot be allocated and GFX draws directly to the screen. In that case, it becomes *really* jerky and it would be a good reason to remove the live-resizing. Maybe it's what you are seeing too.
2 notes to my previous comment: - My machine is slower than yours (266Mhz) and, unless I reach the case mentioned above, I wouldn't call the resizing very jerky. It seems to me fairly nice and smooth, a bit like on Windows. - In the meanwhile, you can disable the live-resizing by holding the Command key pressed.
What I have noticed is that if the content of the window is large in size or complex (as in tables), the resizing becomes really jerky. When the window is not so complex it is not bothersome at all. In fact even when it is jerky it is not a problem for me. The most logical reason to leave out this feature by default, IMO, is that the other Mac browsers do not do this and if it is not difficult to maintain the 'feel' of the current browsers, then it should be done.
Excerpt from a posting on Mozillazine: "M9 is my first experience with Mozilla, and I am impressed. Live window resizing, and realtime re-renderring of the tables as you resize. If ever something in a web browser made my jaw drop, it was this." I'm reopening with a milestone set to M20 in order to keep track of the issue. For now, the status is: if it can't find a way to make it work flawlessly, the feature will not be on by default (you will have to press the Cmd-key to activate the live-resizing). The 2 problems I see are: - When there is not enough memory for offscreen buffers, the display is indeed very jerky (see #3412). - With complex pages, it can be really slow because the reflow is a blocking operation (see #2498 and certainly other bugs).
Grrr! Please read: "if WE can't find a way to make it work..."

People did not seem to like the Live-Resize. It is now only activated when the Command key is pressed. Marking fixed.
