--- Comment #19 from Alex erlkonig@talisman.org --- I can confirm this problem is happening in Lutris on both my Linux (Ubuntu 18.04, AMD Threadripper 16 core, 32 GiB RAM, NVIDIA GTX 1080 driver 390.48, Wine version pba-firerat-3.9-x86_64) and my mom's Linux (Ubuntu 16.04, HP Z400, 12 GiB RAM, NVIDIA - slightly older driver, an older, but not obsolete card, not quite sure which Wine version). Symptom is a gradual increase in the number of polys that should be textured instead ending up in solid colors, usually (always?) all the same one (white, fuschia, red-orange, blue all common), that occasionally changes. Changing texture resolution in game sometimes helps. Rebooting doesn't seem to help. Dropping to minimum graphics settings and then bringing them back up worked (once so far).
Blizzard just stopped supporting 32bit Win7, so my mom's WoW experience is now utterly reliant on Wine (and she hated having to boot Windows anyway).
It's very specific to the BfA prepatch (so far), no issues in Legion. Blizzard changed something.
