Anyone familiar with this bug? And if so, happen to know a fix? AFAIK this bug only effects the PC port of the game--and may possibly be limited to the Steam release. The actual thumbnail jpegs in the save directory are normal, they only appear corrupted when displayed in-game. It's really annoying. Some further notes: The default tile image files in the install directory are likewise normal. As you may notice in the screenshot, the default "blank slot" images (usually a dark-gray logo) are corrupted in the same manner as the saved game thumbnails. Verifying the integrity of the game cache yields no effect. Reinstalling the game yields no effect. Deleting all savedata and starting a new game yields no effect. Removing cloud saves yields no effect. I've found posts in the Steam forums commenting on the same problem, going back to CS1's original release, with zero follow-up. GPU drivers are up-to-date (Catalyst 16.2.1 for AMD HD6870). UPDATE1: Same corruption occurs w/ CS2. Working on Windows 10 x64 operating system. Thumbnails display properly on my old Win8 laptop w/ integrated graphics.
