--- Comment #1 from Andy andysem@mail.ru --- Additionally, with Wine 5.12 I'm occasionally seeing a graphical glitch, which looks like a black screen that moves into the scene (upwards in Z axis), gradually revealing it as it passes different objects, like trees, character models and terrain. It's as if there is a moving Z threshold, after which nothing is drawn.
The game is 1.1.7.1, GOG version.
