Chirbolg: I was experimenting a little bit. This is not character specific but happens for every two handed melee weapon equipped for every character I tested. So in the end it is impossible to play with a two handed melee weapon.
Installation:
Grim Dawn, Malmouth und Forgotten Gods exp.
patched only with Grim Dawn patch
no Mods used every
using Wine 9.0 on Ubuntu
p.s. oh and the monsters are also affected...like inactive Lokarr and so on....
From Zantai on the official forum re the t-poses:
"Considering doing a clean installation has fixed it for everyone suffering from this issue so far, it would appear we were correct to deduce it was on the system end and not a game bug.
It seems there is a problem with GOG’s standalone offline patch files, which we do not generate."
