Symptoms

When loading save games, Wine stops responding.

Reproduction

1. Start game
2. Continue story
3. Wait for story cinematic
4. Loading bar is displayed
5. Observe freeze

Note, I have also tried installing mesa-vulkan-drivers and vulkan-utils from the default ubuntu ppa, but that didn't help at all, so I stuck with the latest drivers from AMD - 18.4.

Additionally, I have also tried starting a new game, but the same issue occurred after the beginning cinematic.
