I'm having the exact same problem, with the same setup.
I did try the Java 7 JVM and the blink / slow problem is gone, but now the font seems choppy (probably not AA). I did research a bit, and for some reason there seems to be some differences on how java 6 and 7 handle fonts.
Would be great if someone else could shed some light in these issues.
I have started to use SquirrelSQL for a PostGresSQL database
and looks very nice! However I have a major problem and I did not find
an answer on the web.
The SQL editor blinks a lot each time I add a new line or I select the SQL text.
With one line of SQL is not a big deal, but if I have 20 lines of SQL it takes 5 seconds to refresh the text box!
java version "1.6.0_43"
Java(TM) SE Runtime Environment (build 1.6.0_43-b01-447-11M4203)
Java HotSpot(TM) 64-Bit Server
SquirrelLSQL Version 3.4.0
I have a mac 64bit retina display.
Do you have any clue what the problem could be?
Thanks in advance,
