 FAQ-O-Matic : Windows-specific :
JBuilder windows don't paint properly. What can I do? |
| Java 2 JVMs on Windows utilize DirectX for AWT (and Swing) classes. These
demands a properly-implemented DirectX driver for the video card. A number
of cards are known to have flaws in their drivers.
See Borland FAQ: http://community.borland.com/article/0,1410,20480,00.html Note: Where the FAQ says to check JBuilder.config, also check jdk.config.

| This problem continues JBuilder 5's bundled Sun JVM 1.3.0 for Windows. The same fix applies to JB5 as to JB4.
It probably also holds for JVM 1.3.1, since the problem is in the Windows video drivers.

| It appears that one of the symptoms has finally been corrected for JDK 1.4. See this Bug Parade item for details:

| A mouse driver called CursorXP is known to cause nasty flickering issues on the entire desktop when JBuilder is in use. Disabling CursorXP eliminates the flickering. This was reported on Windows 2000. 2001-Dec-30 12:44pm gyles19@visi.com | |
| On Windows XP, umcommenting the directX workaround also seems to resolve the following JVM crash:
An unexpected exception has been detected in native code outside the VM. Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x6d043a99 Function name=Java_sun_java2d_loops_DefaultComponent_IntRgbToBgr24Bit Library=C:\JBuilder6\jdk1.3.1\jre\bin\awt.dll
Local Time = Mon Jan 14 16:17:34 2002 Elapsed Time = 16 # # The exception above was detected in native code outside the VM # # Java VM: Java HotSpot(TM) Client VM (1.3.1-b24 mixed mode) # # An error report file has been saved as hs_err_pid484.log. # Please refer to the file for further information. # 2002-Jan-16 10:02am gyles19@visi.com | |
| If you're using a dual-headed video system and experiencing problems, there is an additional workaround for some driver bugs which may help. I don't know exactly what this is supposed to do, but it is suggested for use with some JVMS:
-Dsun.java2d.pmoffscreen=false
I saw this referenced on the java-linux@blackdown.org mailing list.
