[Scilab-users] Bug I of the demos using Scilab 5.4.0 on Ubuntu 12.04

[Uwe Fechner]

Hello,

I like Scilab 5.4.0, but there are some regressions with respect to scilab 5.3.3.

If I start Scilab 5.4.0, click:
- Demos -> Graphics -> 2D and 3D plots -> plot2d I get the following message
in the console:

The graphics is displayed correctly. This error message does not appear with Scilab 5.3.3.

java -version has the following output:

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Server VM (build 20.1-b02, mixed mode)

I use integrated Intel graphics of a core i7.

Any ideas?

Best regards:
