--- Comment #5 from Nathan version2013@protonmail.com --- Wine-4.0-rc4
Testing with a previous FlatOut install. The graphical glitches still appear. Subjectively, they appear less frequent, but they still exist on my system.
After exiting game, among the other terminal messages, the following continuously repeats: 002a:err:d3d:wined3d_debug_callback 0x156280: "glDrawElementsBaseVertex has generated an error (GL_INVALID_OPERATION)".
