Have you posted about this in the forums? Based on the location of the crash (inside libdrm_noeveau) this has the smell of a graphics card driver problem. What card and driver are you using?

Hi,
No, i didn't post in the Forum. Somehow i overlooked the first point - sorry.
I was confused because the 0.18 is working fine.

Should i do this instead or additional to this issue?

$ lspci -nnk | grep "VGA\|'Kern'\|3D\|Display" -A2
08:00.0 VGA compatible controller [0300]: NVIDIA Corporation GM206 [GeForce GTX 960] [10de:1401] (rev a1)
	Subsystem: ASUSTeK Computer Inc. GM206 [GeForce GTX 960] [1043:8528]
	Kernel driver in use: nouveau

Thank you,
Stephan

It looks like there is at least one other person experiencing this, why don't you add your info to this forum discussion:
https://forum.freecadweb.org/viewtopic.php?f=4&t=56394

If we can find out what you have in common that will give devs a chance to debug.

Closing as this seems like a screencard hardware issue.
