There appears to be an issue with black hole warp rendering when SpaceEngine is run via WINE on Linux. I'm currently running WINE 3.3 and have previously tried multiple versions of WINE-staging, WINE-stable, and WINE-devel and they have all persisted with the issue.
More specifically, if BlackHoleQuality is set to anything greater than zero, this issue appears.
It appears to be related to a GLSL shader error of some sort. I tried
winetricks glsl=disabled
and that had no effect on the graphics issue. Then I tried changing some settings in main-user.cfg such as IgnoreShaderBinary, IgnoreSyncObjects, LoaderAsyncTextures, LoaderAsyncMeshes, and LoaderAsyncShaders to no avail.
