Hi Caspar,
Thanks for your reply. I tried to change the rendering properties and it
seems that enabling the "Depth Sorting" option fix the problem temporarily.
Does this give a hint what might be the underlying problem?
The specs are:
Ubuntu 16.04 LTS
OpenGL version string: 3.0 Mesa 17.0.7
Graphics: Intel HD Graphics 620 (Kabylake GT2)
Processor: Intel Core i7-7600U CPU @ 2.80 GHz x 4
