Hi Antoine,

I gave this another go today, doing a fresh reinstall of Kubuntu 18.04 and
installing scilab using sudo as the very first thing I did after a sudo
apt-get upgrade. The same issue persists with ATOMS after doing this.

Following the installation instructions using wget for the 6.0.1 and nightly
build zips gave me multiple java errors ("Scilab cannot create Scilab Java
Main-Class" and X11GLXDrawableFactory issues) and a completely (instead of
"only" partially) install.
Can you give me the details of the error log in the console for this version?
Could it be a problem with the video drivers and mesa?
I had this issue at some point.
Could you try to use:

export MESA_GL_VERSION_OVERRIDE=3.0 ; /path/to/scilab-nightly/bin/scilab

instead of

 /path/to/scilab-nightly/bin/scilab

?

It solved my problems for a while.
No with some later updates, I no longer have this driver issue¹.

Hope it helps,

Antoine
¹ By the way, matlab suffer exactly the same problem on my machine, and I used the very same fix.

I've even done the above with 5.5.2 hoping that the issues would be resolved
with the earlier version.

I'm fresh out of ideas and can only think that maybe it has something to do
with my computer using a Ryzen 1700 processor.

I cant lie, I am bitterly disappointed that Scilab appears to be broken in
this manner.
