Report a bug

No account needed. Your report becomes a public issue on our issue tracker.

If you can, report from inside the viewer with Help → Report Bug. It fills in your version, graphics card and settings, and can attach a cleaned-up log excerpt and a screenshot, which makes bugs much quicker to fix. You see everything before it's sent.

Everything you type here is posted publicly, so don't include passwords or anything private. See our privacy policy.
