2060767 - [Nova] When Firefox shows a dialog box, the semitransparent overlay behind it doesn't cover the page corners

Status: RESOLVED DUPLICATE of bug 2049273

(Toolkit :: Content Prompts, defect)

Description

[Daniel Holbert [:dholbert]]

Attachment: testcase 1

STR:

1. Load attached testcase and click the button. (Or alternately, Ctrl+P to bring up a print-preview dialog on any page.)
2. Look at all 4 corners of your viewport. Is the page background-color properly darkened (like the rest of the viewport) in all of those spots?

ACTUAL RESULTS:
Some corners are not darkened. The semi-transparent overlay that attempts to darken the full viewport has rounded corners at all 4 corners.
Whereas the actual viewport (the thing it's trying to cover) has some square corners (maybe a few, or maybe all of them, depending on whether your window is maximized; and whether the compact sidebar is showing or hidden; and probably more factors)

EXPECTED RESULTS:
Semi-transparent overlay should cover all of the corners of the viewport.

The Bugbug bot thinks this bug should belong to the 'Core::Printing: Output' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Here's a screenshot. Note the top-left and top-right corners of the viewport are square, so the rounded corners on the overlay let the color shine through.
Even the bottom corners have a sliver that shines through, despite the corners being rounded.

Nope. Printing is one type of dialog that triggers this, but it also affects alert and other dialogs.

Let's put this in Toolkit::Content Prompts; hopefully that's the right spot, or at least closer.

Here's a screenshot of a maximized window. As you can see, all 4 corners of the viewport are "square" in a maximized window, and yet the overlay has rounded corners, so some of the page background shines through in each corner.

Thank you for the report, I believe this is describing the same issue as bug 2049273.

Yup, that bug's patch fixes the issue for me. I filed bug 2062447 on one remaining issue.
