When playing The Witcher 3 (from Steam) on a Kabylake Core i7-8650U on a Dell
notebook with a UHD620 I get a inconsistent mesh flickering. It occurs in some
places only, and is repeatable. But the flickering is very random.
I did a video recording of the issue here:
https://drive.google.com/file/d/1Y8TBaMtc-dP4N-GRuHcR3OZzx9JaiODg/view

This is using DXVK 0.94 bundled with Proton 3.16-6. (and 0.96 too)

The Witcher 3 from Steam, 1280x720 all lowest except for texture resolution
which is medium.

System information:
    GPU: Intel UHD620
    Driver: AMV from mesa git
    Wine version: Wine 3.16 bundles with Proton 3.16-6
    DXVK version: DXVK 0.94 bundled with Proton 3.16-6 and DXVK 0.96
    OS: Gentoo Linux, 4.20.4, KDE5 desktop with compositing disabled.
