Thanks for filing this bug, but it isn't super useful without a minimized test case or screenshots. Servo is still lacking many features (fully implemented flexbox, grid, etc), so it's natural that the layout of some sites is broken. If you are interested in digging into this failure a bit and adding debugging information we could reopen this issue and start working on things -- but many sites are broken and we can't have a bug for every broken site at the moment.

[mrobinson]

Sorry. I'll reopen this one as it isn't layout-related and it's a bit more straight-forward to debug.

@mrobinson Servo gives me two logs, one inside the GUI renderer and one on the terminal.

• The log text in the GUI renderer can't be copied, why?
• The terminal log is useful?

Selection support hasn't been implemented yet, so only a screenshot could work now.

• The terminal log is useful?

Yes, it's useful. It's more or less the same output.

@mrego The screenshot log will be incomplete, you need two screenshots.

I don't get the crash log on the terminal, IDK why.
