1792560 - [fission] Transformed (translated) frame contents are blurry since fission isolation

Status: NEW

(Core :: Graphics: WebRender, defect)

Description

[Kestrel]

Attachment: Comparison showing a normal frame and a blurry translated one

STR:

1. Open the attached test case derived from the login captcha at https://uk.wallapop.com.

The translated captcha frame is blurry, including text, PNG image and checkbox border. Opening the frame in a separate tab or taking a screenshot using the built-in screenshot tool does not have the issue, nor with fission.autostart = false or fission.webContentIsolationStrategy = 0 (no frame isolation).

Regression window (using fission.autostart = true and fission.webContentIsolationStrategy = 1):

When I run the attached test case I don't see anything inside the iframes, and I get:

Uncaught ReferenceError: recaptcha is not defined

On the console, even on a clean nightly profile with no addons enabled.

Does the test case still work and repro for you?

Comment 6

[Timothy Nikkel (:tnikkel)]

The testcase no longer works for me and I remember testing and it working before. Maybe an update in the recaptcha embeding api?

Updated test case, still reproducible.

Comment 8

[Mayank Bansal]

Nothing loads in test-case2 for me now. Is this still reproducible for you? If yes, can you attach an updated testcase?
