I encountered a weird case with Everspace (GOG). if I run the game directly in terminal with ./start.sh --syslibs, cutscenes would work perfectly. But if I use Lutris, the cutscenes become black (with audio working). I tried specifying Working Directory but still got black cutscenes. I didn’t forgot to put --syslibs in Arguments. Can’t think of what would make the results different. Any ideas?
I also own the game and I’ve tried to replicate your problem without success. Weird… I’m currently running ubuntu 20.04 with the latest graphics driver. What’s your linux distribution?
That’s really weird because I also use Ubuntu 20.04.
