Editor text "stuttering"/GUI problems

[bds]

Hi all,

Apologies if this has been discussed before - I'm unable to find any references to this issue here on the forum. In the last two releases of oXygen Editor v 14 (2012062215 [1] and 2012080717 [2]), I'm getting weird text/UI behavior when I scroll horizontally and/or vertically (screenshot here: http://i.imgur.com/UU9Gr.png [3])
OS: FreeBSD 9.0
Java: OpenJDK 1.6.0_32

Please let me know if I can provide any additional information to help diagnose this problem. Thanks in advance for your time.

Cheers!

Hello,

From the screenshot this looks like a repaint issue.
If you start the application from a terminal window, do you see any error messages or Java stack traces in the terminal after the problem occurs?

On other platforms this type of error (garbled editor content) would sometimes occur because of a text anti-aliasing setting. Could you please try various anti-aliasing settings in Options > Preferences, Fonts, Text antialiasing?

In addition, have you considered installing Oracle JDK 1.6 and running Oxygen with it?
http://www.freebsd.org/java/install.html
I've found detailed instructions for installing/building Oracle JDK 1.6 on FreeBSD here (though they are for an older version):
http://devreview.net/0306/how-to-instal ... n-freebsd/

I'm asking this because during development Oxygen is first and foremost tested against Oracle Java SE 6, so we know it to be perfectly stable with this particular JRE.

Regards,
Adrian

Hi Adrian,

Thank you for the reply. The only ERROR I'm seeing from a terminal start is due to "the hunspell library or dictionary could not be loaded, due to java.lang.UnsupportedOperationException: Unknown OS/arch: freebsd/amd64".

I've tried all of the options under Preferences > Fonts > Text antialiasing with no luck. I'll explore building JDK 1.6 and will report back.

Thanks again for your time & assistance!
Cheers!

Hi,

The error you see in the console is unrelated to this problem.
This error message appears because Oxygen does not include a native implementation of the hunspell spell checker for FreeBSD.

Let me know of any progress with the JDK.

Regards,
Adrian

Adrian --
thanks again for your help. I've switched to an updated graphics driver and the Oracle Java and I'm not experiencing the problem any more. While I can't say which provided the fix, I feel better using the officially supported Java.

Cheers!
