New hashcat freezes or very slow

[Kangaroot]

Updated Hashcat to v4.1.0-3-g63defd1c and it started freezing my computer or running slow.

Using usual command, i.e. hashcat -m 2500 -a 0 -w 3 example.hccapx dictionary.txt it then either freezes computer or running incredibly slow at 10 h/s.

I have Ryzen 1800x + 2x GTX970, Ubuntu 17.10. Only just started after update latest hashcat version. Previously on hashcat --version it returned pull/1273/head.

Please advice how to pull back to previous version or fix the problem on the new version.
