I have Ubuntu 16.04.2 LTS with mate desktop. I installed DraftSight with these instructions:

https://www.3ds.com/products-services/draftsight-cad-software/free-download/

I downloaded deb file for ubuntu in installed it with

sudo dpkg -i draftSight.deb

Installation went without any errors.

When I start the DraftSight it asks activation. I fill all fields and press "activate" and then after few secods the DraftSight crashes probably before sending any email.

Console output is as follows:

/opt/dassault-systemes/DraftSight/Linux/DraftSightCould not parse stylesheet of object 0x21f5bd0Could not parse stylesheet of object 0x21f5bd0[15707:15707:0312/233839.681371:ERROR:child_thread_impl.cc(762)] Request for unknown Channel-associated interface: ui::mojom::GpuMainCreated new window in existing browser session.

How can I fix this issue? Are there any packages that need to be installed before installing DraftSight?

Thank you for your support.
