Steps to reproduce:

If you run the WebDriver:TakeScreenshot command with default parameters other than full=true on this page: https://www.blueorigin.com/latest/gallery

You will get a screenshot that is only the height of the viewport. The width is the width of the viewport like expected, but the height will be just the viewport and not the full page height.

Hope this helps, happy to provide more info if needed.

Actual results:

The geckodriver output probably won't be helpful here, so I'm just going to describe this issue. Though here is the request that was made.

1574450485733 webdriver::server DEBUG -> GET /session/623573bc-cfe8-453d-96fc-134fa8351d0d/moz/screenshot/full

Expected results:

The screenshot height should have been larger than the viewport.

Sorry I realized I could given better reproduce steps.

Geckodriver version: v0.26.0
Firefox version: 70.0.1 (64-bit)
Platform: Windows 10

1. Navigate to: https://www.blueorigin.com/latest/gallery
2. Send screenshot full command
3. Observe returned png height is that of the viewport and the image is cutoff.

For full screenshots we take the bounding client rect of the document element which is for this website:

{"x":0,"y":0,"width":1265,"height":988,"top":0,"right":1265,"bottom":988,"left":0}

It would work when we would use the body.height and body.width here:

Note that the specified page is huge and as such seem to cause a crash in GFX as reported on bug 1598731. We have to get this fixed first.

Actually this is a dupe of bug 1571424.
