Hi Tim,

I had similar problems with Opera which was badly drawn resulting in a thick 
black line across the tab bar and other problems with the tool bars not  
displaying correctly.

I eventually resolved the problem by installing the packages below
gtk2-engines-murrine
murrine-themes

Having installed them open tde control centre (system settings) appearance/gtk 
styles and fonts. Under GTK Styles choose use another style and chose one of 
the Murrine styles. I chose MurrinaBlue but probably any of the murrine 
styles will work.

After a reboot I found that Opera was fixed.

This was with Xubuntu Lucid 10.04 and Precise 12.04 both with TDE 3.5.13.2

Hoping this may resolve your problem.

Nigel.
