https://bugs.winehq.org/show_bug.cgi?id=45278 --- Comment #3 from Jan Havran <havran.jan(a)email.cz> --- Hello, I finally had some time and successfully found the problematic patch. It is the patch "wined3d-Indexed_Vertex_Blending" as I expected, applied from wine-staging-3.9 to wine-3.9 by script "patches/patchinstall.sh". Why I focused on this patch you ask? Well, because this patch prevents game from crashing in certain missions (but the patch is not necessary for all missions). For more info about crashing, see bug #9337 [1]. There was also one regression bug in this patchset in Wine-Staging 3.3 (fixed by Zebediah Figura), see bug #44712 [2]. Tested both demo and full version of Vietcong.
