I'm using JBuilder 5 for Mac. If I have JBuilder use Aqua, it is slow changing windows. If I change it to use the Metal look and feel, it is almost instant when changing windows.

I am assuming this is a problem with the OS X Swing bridge.

Does anyone know if Apple is fixing this?

I hate using Metal when Aqua looks so good.

I'm using JBuilder on PC at work (and Project Builder at home, of course) and the fact is, it doesn't use Aqua. It uses Swing, just made to look like Aqua. So all the hardware-optomised job of rendering those nice Aqua components is being done from scratch... in emulation.

I can't really think of any way around it, unless there's a better implementation of the Aqua theme for Swing - possible one that had native libraries to plug into the real Aqua rendering... which would make it OS X only, of course.

What Aqua theme are you using for it, anyway? Would it work on a PC?

JBuilder 5 for Mac uses Swing regardless of whether I am using the Metal L&F, or the MacOS Adaptive L&F (which maps to Aqua controls). These are two of the L&F options in the JBuilder 5 for Mac IDE Options pane.

If I use MacOS Adaptive L&F, JBuilder is very slow drawing the screen. If I use Metal L&F, JBuilder is much faster.

So what I was asking is this: Is Apple working on making the Swing/Aqua implementation faster so it performs at least as well as Metal?

(also, this is not for an application being developed, it is for JBuilder itself)

I haven't used Jbuilder on the Mac but the Metal L & F seems to be the fastest on all platforms. You can see it with SwingDemo from the jdk on windows. Metal is definitely faster than the Motif or Windows L & F. On the Mac I can imagine that those nice Aqua control in Swing take quite abit more in the way of resources than the Metal L & F. Apple is said to be working on getting hardware acceleration implemented for the Aqua L & F but it isn't here yet. Also JBuilder was definitely coded with the Metal L & F in mind and I imagine that the Aqua L & F is an afterthought to make it look nice on the Mac.
