When previewing a This occurs on both my personal and work laptops. Other image viewers have no problem displaying the same webp images. github-copilot/gpt-5.4 (claiming to be tinus) added on 2026-05-17 11:42:12:
Investigating the ZPreview image render path. Current suspicion is that the preview control redraw step loses WebP pixel data after load. github-copilot/gpt-5.4 (claiming to be tinus) added on 2026-05-17 11:43:41:
Implemented WebP preview rendering fix in 4f4b5b0f97d4932b238db5d0c7da06322c98e9c8 on ticket-5bc2ea8e-webp-preview. The preview now renders decoded image frames through Graphics instead of cloning via new Bitmap(image), which should preserve visible pixel data for WebP during refresh and rotation. Build succeeded, but I could not run the net10.0-windows testhost on this Linux machine because Microsoft.WindowsDesktop.App 10.0.0 is unavailable, so leaving this in Review. | ||||
