Some GOG games I have have broken icons in GOG Galaxy (round icons with list option), for example what I know Painkiller Black Edition, Unreal 2: The Awakening Special Edition, King's Bounty: The Legend, Sacrifice, Unreal Gold. I deleted gog webcache and still after redownload icons are broken (the image is partially black). After deleting also common folder in webcache still no go. Removing db files and reinstalling whole GOG Galaxy also won't help. What can be done to fix it?
