Affected versions

• Firefox 85.0.2
• Firefox 86.0b7
• Firefox 87.0a1

Affected platforms

• macOS 10.15.7 & 11.2

Steps to reproduce

1. Launch Firefox
2. Access any Google Spreadsheet
3. Pinch the page or scroll it

Expected result

• Some edit/menu icons will disappear after pinching/zooming

Actual result

• All icons are visible after pinching/zooming

Regression range

• Will see for a regression

Additional notes

• The issue can be seen in the following attachment
• The issue is much more easier to reproduce by pinch.

Looks like those images are draw as background images from an svg sprite sheet. Only reproduces with webrender for me.

./mach mozregression --pref gfx.webrender.all:true apz.allow_zooming:true --profile-persistence clone-first -a "a google spreadsheet"

-> bug 1662062

Hmm, wonder if including the pinch zoom resolution makes some math go funky somewhere?

Pinch zoom a 74px x 6523px svg image is all that's needed to reproduce, we probably exceed a size threshold and don't allow decoding.

In a debug build plenty of these in the console

Timothy, did you make any progress?

This should be fixed now, can you confirm?

Yep, cannot reproduce it anymore on macOS 13.3 with Firefox 112.0 and 113.0a1 (2023-04-03). Closing it as WFM. Thank you!
