Polygons are not flat on the original CPC implementation (check the screenshot). However, the stipple pattern look incorrect, so I will investigate.

OpenGL rendering looks correct (attached a screenshot), but the OpenGL shader renderer has these incorrect patterns.

I believe this was fixed in this commit: https://github.com/scummvm/scummvm/commit/3dd927df06021779c8bd45c34a1ecc1d1ea33fc5

Please test it (wait for tomorrow for a daily build or compile your own) and let me know so we can close this one.
