1786637 - White flash when clicking + in toolbox Style Editor (dark mode)

Status: RESOLVED DUPLICATE of bug 1782596

(DevTools :: Style Editor, defect)

Description

[Ed]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:104.0) Gecko/20100101 Firefox/104.0

Steps to reproduce:

• open the toolbox in dark mode with either ctrl-shift-c or ctrl-alt-shift-i
• click Style Editor and then click the + sign to create a new stylesheet

Actual results:

A white flash in the toolbox window sometimes happens when clicking Style Editor; if it does not happen then, it always happens when clicking the + sign to create a new stylesheet.

Expected results:

There should be no white flash. Testing with FF portable, I determined that this problem is not present in 101 and is present in one of the 102 versions. Will try to pin down which one.

Problem started with 102.0 and persists through 105.0b1. It had affected Nightly also, but appears to be gone in 106.0a1.

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

Although it seems to have been resolved by bug 1782596.
