Comment 6 for bug 455615

@Onkar,
No i don't have idea at what SVN revision was it fixed.
I can only tell you that the bug is fixed at GC class:

org.eclipse.swt.graphics.GC.java, At "initCairo()" method
where cleary, there is an IF condition checking if GTK version is lesser than 2, 17, 0
I have tested override this methood content to 3.5 version of SWT, and the problem was gone.

However after write this post, i saw that there are other problems than graphics, ( also fixed on 3.6 )
but not sure where are they fixed.

These other problems, are also reproducible in eclipse (not only in tuxguitar).
some buttons just don't works with mouse clicks. ( yes with keyboard )

In tuxguitar you can reproduce the problem:
* Menu: Tools -> Plugins
* Select any plugin, and click "Info" button.
It only gain focus, but listeners are not fired, but if you press SPACE or ENTER listeners work.

In eclipse ( may depend the version, i don't have it from repositories )
* Just open a source file, and press "Ctrl + F"
* Type a search text, and click "Find" button..

I found problems on some other eclipse buttons too. but it's hard to give you steps to reproduce them.

I had planned to release tuxguitar 1.2 this weekend but now i don't have idea what to do with this problem..
It seems that SWT versions lesser than 3.6, just can't coexist with new GTK versions.

@MasterProg,
The splash screen sometimes works.... but sometimes don't, even in 3.6
i don't know exactly the reason, but i was able to fix it from tuxguitar code calling an update inmediatly after the windows opens.
and this fix yes works for lesser SWT versions of GTK.
