1671750 - Tab Manager has lines under each button when the mouse is moved over them in an upwards direction on macOS

Status: RESOLVED DUPLICATE of bug 1688899

(Core :: Widget: Cocoa, defect, P2)

Description

[lolrepeatlol]

Attachment: Screen recording of the issue

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

I opened the Tab Manager and moved my mouse over the options in an upwards direction.

Actual results:

Lines became visible under every item.

Expected results:

Lines should not have appeared.

I am using WebRender but this also happens under OpenGL. It happens in the latest Nightly, version 83 2020-10-16 (and has happened for the past couple Nightlies, sorry for not posting earlier). It also happens in beta 82. I have checked on Windows and this issue does not occur. I also do not see this issue on other menus.

Disclaimer: This is on a Ryzen Hackintosh which does have occasional graphics issues with its patches. (I apologize if this does not happen on normal Macs.)

Specs if it helps:

• Ryzen 7 1700
• MSI B350 PC Mate
• 16GB RAM
• Gigabyte RX 5700 XT
• OpenCore 0.6.2, macOS Catalina 10.15.7, latest version of AMD patches

This is reproducible on Apple hardware (MacBook Pro 15-inch, 2018) running Big Sur Beta 10. I hit the problem on Nightly 83 and Release 81.
