Speed dial crashing browser

[brita]

A lot of Google Drive related websites crash the browser if I try to add them to speed dial (such as docs.google.com, or slides.google.com, though strangely not drive.google.com).

The crash seems to happen a few seconds after I add the speed dial entry, when Vivaldi tries to generate the thumbnail. It also crashes if I try to click the entry.

If it helps, here are the last few lines of command line output when this happens:
