Hi there,
I’m just wondering if any of you guys had any problems with the accelerated translucent managed images (enabled with -Dsun.java2d.translaccel=true option), in 1.5 beta1?
There’s a slight chance that we may turn it on by default in 1.5…
Are there performance changes with this option compared with Java 1.4.2? Any known issue or hint?
The trick would be to turn it on by default in the next beta and see what happens in terms of bug reports. After all, it can be turned off just as easily as it can be turned on.
It’s sort of a secret as it is… so I understand why you ask here, the people in these forums are probably the only ones that have ever tried it.
With -Dsun.java2d.translaccel=true my swing gui is completely messy. I had to turn it off.
I noticed some little speed improvements is some little fields of application btw.
HINT: Resetting the look and feel helps to restore the gui.
Cheers,
Mik

You report the bug, right?
And provided sample code that showed the problem?
And mentioned your graphics card model and driver versions?
They aren’t going to fix stuff unless we “officially” tell them it’s broken.
javazoid, please do elaborate on your problem. This is the first time we heard of something like this.
As swpalmer mentioned, please post your video board, driver and dx version, the OS, what application were you running, which toolkit (swing, awt, your own), on what jdk version.
Can you produce a test case?
Hello,
I did some deeper check and I discovered it as being a 1.5.0 b1 look and feel problem. -Dsun.java2d.translaccel=true does not change the result.
Take a look anyway
Under jdk1.5.0 b1
Under jdk1.4.2_04

I’ve come across several problems with Swing in 1.5. Mainly layout behaviours being incorrect, possibly to do with image sizes.
Cas 
Apart from 1 area being a deep grey, and the other a light grey, what is the problem with those 2 pictures???
oh nvm, 1 of the comboboxes is knackered as well… so the top picture is 1.5 then
Yes, Abuse, just look at the top of the first picture and you’ll see “Under jdk1.5.0 b1” ;D
But this has little to do with transaccell, fortunately.
First one is using the gtk look and feel (you have a setSystemLookAndFeel lurking somewhere in that panel code I guess?), the second one metal - so what’s the problem really? ???
(Except that the gtk theme used by 1.5_beta1 is quite ugly 
Off topic: Anyone know why sun choose to implement gtk instead of (IMNSHO) the much prettier kde themes, for instance kde3.2+ plastik and keramik which are truly awesome compared to swing/gtk bluecureve/win32/xp?

Issues with the KDE licence?
My understanding is that GTK L&F is not supposed to work on windows in 1.5.
Could be, noticed that ibm has a java qt/kde binding (i.e. swt uses qt/kde instead of gtk if I understood it correctly) available that they can’t release due to unclear licences - a real pitty
