After a fresh install of CentOs as well as after updating a running installation, DeskApp is no longer starting.

Tested inside VM (KVM):
OS: CentOS 7.6.18.10
Deskapp: 2.1.7 (Chromium 69.0.3497.100) & 2.1.9
KDE & XFCE

Trying to start it from terminal results in following errors:

[15676:15676:1231/080138:ERROR:sandbox_linux.cc(381)] InitializeSandbox() called with multiple threads in process gpu-process.
[15647:15647:1231/080138.321461:ERROR:gpu_process_transportfactory.cc(1007)] Lost UI shared context.

In the syslog I get a segfault error 4 in libc-2.17.so

For me it looks like like a problem with Chromium integrated into the DeskApp. I tried several options (like --no-gpu, etc) to start the DA, without success.

Anybody can confirm these errors and/or has an idea/workaround how to solve it?
