https://bugs.winehq.org/show_bug.cgi?id=46558 --- Comment #8 from BabbleBones(a)gmail.com --- Issue has been found! The game decodes a 16 bit grayscale png and uses that for height information on the planets. Somehow the png may be getting truncated on read. What it truncates into I am not sure but it may be an 8 bit value that would wrap around and swing the terrain generation in crazy directions. Saving the images back to disk as 8 bit grayscale png seems to solve the issue. Please see: https://github.com/ValveSoftware/Proton/issues/1792 How is png conversion from 16bpc gray to 8bpc gray handled? Is it an external lib or internal implementation? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
