--- Comment #79 from Sergio Callegari scallegari@arces.unibo.it 2010-12-11 15:53:58 CST --- As of wine 1.3.9, for what concerns the transparency of the icon background in the application LTSPICE (invoked with the -nowine switch to make it run in the standard MS windows way, rather than adopting wine-aware hacks) the bug is still present.
See it by
1) downloading the application that is free to use from http://www.linear.com/designtools/software/ and install it
2) start it with the -nowine switch
3) File -> new schematic
4) Simulate -> control panel
5) observe the background of the icons in the control panel tabs
6) retry on windows or without the -nowine switch to see how they should be.
