Details

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:66.0) Gecko/20100101 Firefox/66.0

Steps to reproduce:

Having gfx.webrender.all set to true. Open https://musicmap.info. Zoom in using either the + button on the right or using the trackpad on my macbook.

Actual results:

The zooming is visually sluggish. With gfx.webrender.all set to false it's better but still not as good as with safari.

Expected results:

The zooming should be more smooth.

Turning on gfx.webrender.blob.paint-flashing shows us having a really bad time here. However, it's probably ok enough to ship the MVP
