|
|
If anyone is still interested, here's more info from the Java graphics
experts:
----------------------------%<-----------------------------
The following from the xorg.log file tells us that EXA hw accelerated
rendering is enabled:
(II) EXA(0): Offscreen pixmap area of 84934656 bytes
(II) EXA(0): Driver registered support for the following operations:
(II) Solid
(II) Copy
(II) Composite (RENDER acceleration)
The EXA drivers are still very buggy so this is likely a driver bug.
Please try switching to XAA and see if it makes any difference.
(add Option "AccelMethod" "XAA" to xorg.conf, see 'man xorg.conf').
----------------------------%<-----------------------------
Another work around for this issue is the previously mentioned
"-J-Dsun.java2d.pmoffscreen=false" switch.
One more time: thank you all for your help!

bug is the same there.
Code:
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)
But it works when I use the parameter, just like the last poster
reported.
Code:
-Dsun.java2d.pmoffscreen=false

Thank you, I will try that tomorrow!
By googling for that, I found that some people have the same problems with their SAP Gui

The combination of Ubutnu 8.10 and intel drivers seems to be the issue here. |

Hi there!
I have the same problem. Spending few days researching the problem I can state that:
1. The problem is related with Xorg 7.4. If you use earlier version - everything is OK
2. The problem is related to intel graphic cards (probably intel driver) and not SIS and NVidia (those types I have). With Xorg 7.4 and some other card - no problem.
3. The problem is related to Java applications that use SWING. Eclipse does not this bug because it uses GTK to draw the interface
4. Does not matter which Java version you use - 1.4.x, 1.5.x, 1.6.x - same (d)effect
If someone of the developers needs more information - let me know I'll provide whatever I can.
Currently I'm forced to use Eclipse for PHP and Java development I do which is a big pain in the ass for me. Hope there will be a solution soon!
<edit few minutes later>
Huge Thanks to Jan Chalupa!!! Adding folowing line:
| Code: | | Option "AccelMethod" "XAA" |
in Screen section of xorg.conf definitely solved the problem in NetBeans and in ZendStudio. Looks like this really is a Intel's driver problem.
