Steps to reproduce:
This error is happening in two places. In the URL bar and with SVG graphics. When the URL bar and SVG graphics are larger than approximately 2040px wide, vertical bars start to eat into graphics. This results in 8 well rendered segments bisected by visual artifacting.
I am on an M1 Mac Mini (2020) running MacOS 11.3 and FireFox 88.0 (64-bit)
To reproduce SVG issue:
- Visit a CSS-Tricks page: https://css-tricks.com/you-can-label-a-javascript-if-statement/
- Ensure the viewport is wide, say 2400px wide.
- See artifacting

To reproduce URL bar issue:
- View a really long URL like https://duckduckgo.com/?t=ffab&q=css+tricks&iax=images&ia=images&iai=https%3A%2F%2Fimg-cdn.tnwcdn.com%2Fimage%2Ftnw%3Ffilter_last%3D1%26fit%3D1280%252C640%26url%3Dhttps%3A%252F%252Fcdn0.tnwcdn.com%252Fwp-content%252Fblogs.dir%252F1%252Ffiles%252F2015%252F08%252Fflexbox.jpg%26signature%3D51f46bd2088d4eca6698335b23174bd5
- Make sure you are at a wide viewport. Wider than above because the URL bar is padded by some other chrome. Replicated at 2500px wide.

Expected results:
There should be no rendering gaps or artifacting.

The Bugbug bot thinks this bug should belong to the 'Firefox::Address Bar' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Looks like a graphics issue, especially the urlbar screenshot. Over to Graphics for further triage.

The url bar one sounds like it is bug 1700063. Could you test nightly to see if it's fixed?
