511617 - [10.4] Stray line at the end of a linear gradient with fractional box height, dependent on window width

Status: RESOLVED WONTFIX

(Core :: Graphics, defect, P2)

Description

Attachment: testcase

I'm seeing this on 10.4.

Load the testcase and change the width of the window. At certain widths you'll see a red line which shouldn't be there.

This bug can also be seen in the downloads window on the "Clear List" button (which uses a CSS gradient since bug 508739): At certain window sizes there's a white line in the pixel row directly above the button's bottom border.

I couldn't reproduce this on 10.5 (with roc's machine) either.

I don't think this actually blocks the release. It's probably not a regression.

Ah, I thought it was a regression. blocking-
