@Niklas can you please take a look at this issue? it seems that Bug 1763484 could be the culprit.

This issue also occurs on Windows apparently, but only if we set the Zoom level to 120% or higher.

Comment 3

[Niklas Baumgardner [:niklas]]

Yeah, the error is occurring because the resulting image size is greater than the canvas size.
I'm looking into fixes for this in bug 1743887.
In the meantime, if you flip screenshots.browser.component.enabled to true in about:config, it should work as long as the zoom is 100%.
