I'm having trouble with this game on both Mac (Mac OS 10.11 on a Macbook Pro from 2011, AMD Radeon 6750M) and Linux (Ubuntu 16.04 on a somewhat older Dell 6400 with NVidia Quadro NVS 160M). Both machines run Eldritch just fine, but with this game the display comes up garbled. It makes no difference whether I start it in windowed or fullscreen mode. The game is rendered behind(!) the visual garbage (it can be seen through the garbage sometimes, depending on the garbage...), it looks like there is a framebuffer overlayed onto the game which is not initialized or something like this. If I can provide more info, just ask ahead.
