current svn trunk has a change by Gregory which draws the window while resizing, the content is updated at intervals so not to be too cpu consuming.

yes, live window resizing tends to be slow, especially if there is no shared memory. All the first MacOS X versions were exceedingly slow in resizing even on  back-then decent computers. On exported display it is of course unusable.

When GNUstep handles decoration we don't display anything, I would like at least a border line: windowmaker lets you choose between solid window dragging and a wireframe around (in this case we speak of dragging and not resizing and the two should be consistent in my opinion)

When doing a resize while the window manager handles the windows borders we actually try to redraw the content of the window, when the border dragging leaves us time for that. So most likely it should also be possible, when we handle the window border.
Somebody will need to adjust the implementation of resizeWindowStartingWithEvent: on GSStandardWindowDecorationView to handle periodic events and call
[window setFrame: newFrame  display: YES];
when that event gets fired. As I am never usind this setting, I hope that somebody else will volunteer to work on that code.

I'm wondering if periodically displaying the window during the resize would work and not be too expensive.   The problem is, on slow machines this would be a dog.

As the title says, the resized window isn't displayed while resizing.  A user pretty much has to guess if they have the wanted window size, or do a trial and error routine.

Happens with all backends, and for as long as I can remember using that setting (at least a year now).

Let me know if more info is needed, I figured this was fairly self explanatory.
