This is something that has been bothering me for a while, and maybe I am not the only one who has noticed this. I have compiled the CVS HEAD version and the 1.2.3 version on the same old machine (a Pentium 200) and the CVS version is significantly slower than the 1.2.x version. Of course, there is a lot of debugging code in 1.3.x, but I am surprised that the differences are so significant on that machine. Some simple operations such as accessing the menus (both the pop-up menus and the menus from the toolbox), refreshing the toolbox or refreshing the contents of the docks take approximatively 5 to 6 times longer than with the old 1.2.3 version. The delays are significant enough to disturb the normal flow of operations (at least for me). Does anybody know what could be the source of these delays? Is this due to the GIMP itself (debugging code, new user interface) or is this due to the fact that the CVS version uses GTK+ 2.0 instead of GTK+ 1.2.x? -Raphaël
