Openjdk very slow

[Nick Payne]

I'm running Lucid beta 1 x86 patched as of this morning and using jEdit 4.3.1 for editing source code files. If I use openjdk for Java, updating of the jEdit text area is glacially slow. If I execute


sudo update-java-alternatives -s java-6-sun

to swap to using Sun Java, then the text area updates at quite acceptable speed.

I have noticed this also.

I have a feeling that it's specifically painting tasks that are happening slowly.

Try running with the following option:
java -Dsun.java2d.pmoffscreen=false

This worked for me, perfectly acceptable speed now.
