Ubuntu 16.04 LTS with kernel 4.13.0-36-generic (hardware enablement)

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
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.https://i.imgur.com/0Sys03v.jpg
This is with black hole quality set to low (or zero in the config file). Looks correct.https://i.imgur.com/gxfHKjS.jpg
This is with black hole quality set to anything but low. Looks artifacted and corrupted. The look of the corruption changes depending on the orientation of the camera and distance from the black hole.
