--- Comment #9 from Meghan Pietila pietila.meghan@gmail.com --- Appears to be FIXED on my machine now.
AMD Radeon HD 7800 series card. "DirectX 11" and "DirectX 11 Legacy" both available in WoW system settings dropdown, but historically non-legacy has serious framerate issues so using legacy.
1. Ran "sudo apt-get install --dry-run wine-staging" to check for missing dependencies; I have 5.19 installed and ubuntu wine-staging is now pointing to 5.20 but it seemed worth checking.
Out of the list of dependencies, the following seemed related to errors I was getting (graphics / kerberos), so I manually installed them from commandline:
libglu1:i386 (redirects to libglu1-mesa:i386) libgtk-3-0:i386 (added 18 other dependencies)
libgssapi-krb5-2:i386 (added 4 other crypto and krb dependencies)
On restart, the kerberos errors were no longer displaying in the logs (probably unrelated anyway), and instead of getting rainbow boxy effects, the problematic textures were green and no longer boxy.
2. Noticed in winecfg that it was set to Windows 7. Changed to Windows 10 and restarted - everything now works in d3d11-legacy - water, spells, druid moonkin form with "glyph of stars" applied...
