This sounds like it could be an issue with recent versions of the NVIDIA proprietary driver (that would explain why 16.04 and 17.10 don't exhibit the issue).
Unfortunately I don't have NVIDIA hardware, so I can't reproduce the issue (the Khronos WebGL conformance tests for readpixels pass with an Intel GPU). I couldn't find an upstream bug report that matches this issue, would you mind filing one at https://crbug.com/ and linking it here? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764648 Title: Read pixels broken in Chrome/Chromium on 18.04 using the NVIDIA driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1764648/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
